性が悪かった。Conventional structure and its problems Conventional thick film resistors are constructed by forming a planar rectangular resistor (1) and a lead wire (2) on a substrate, as shown in Fig. 1. ing. (3) is a joint where lead electrodes (2) (2) are formed on both ends of the resistor (1). Due to this structure, the only way to adjust the resistance value is to perform trimming (9)f, but if the resistance value is too high, adjustment by trimming is impossible. On the other hand, the resistivity of thick film resistor paste changes depending on the size, viscosity, solid content, etc. of the particles that become the resistor, and it is difficult to determine the desired resistivity, resulting in large variations in the resistance value. There is a tendency to put it away. Conventionally, this adjustment involved removing the paste from the screen and controlling or increasing the viscosity with a diluent such as thinner. However, this method was too unproductive.

Components that are substantially the same as those described in FIG. 1 will be designated by the same reference numerals and their description will be omitted. In FIGS. 2 and 4, one end of the resistor (4) is formed into a step-like irregularly shaped part (5), with a first step part (6) having the narrowest width and a second step part having a wider width than the first step part (6). It has a two-step part (7), and the other end part (8) extends into a rectangular shape with the same width as the middle part. The extraction electrode (2) is in contact with only the first step part (6) at one end of the resistor (4), and is in contact with the gold mine at the other end.

As shown in FIGS. 3 and 5, the resistor (4) is formed by shifting its position to the right in the figure, and the extraction electrode (2) is formed at its original position. Then, at one end of the resistor (4), the lead electrode f21 K is formed at the first step part r6) and the second step part (7).
At the other end, they touch at a gold mine as in the case of Fig. 2. In this way, the resistance value can be lowered.
この様に１抵抗体（４）の印刷形成位ＩＲヲずらせるに

印刷面のホルダーの位置を微少に動かすことにより容易
に行える。In order to shift the printing position IR of one resistor (4) in this way, you can either shift the position of the screen attached to the printing machine, or
This can be easily done by slightly moving the position of the holder on the printing surface.

きる。Furthermore, in order to improve the accuracy of the resistance value of the thick film resistor thus formed, trimming (9) may be performed as shown in FIG. That is, the error can be reduced by trimming on the other end (8) side.

形状が逐次変化しておれば良い。In the above embodiment, the formation position of the extraction electrode is kept constant and the formation position of the resistor is shifted. However, conversely, the formation position 1 of the resistor is kept constant and the formation position of the extraction electrode is shifted. The key is to shift the relative first place N. Further, although a step-like shape is shown as the shape of the irregularly shaped portion (5), it is sufficient that the shape changes successively in the longitudinal direction at one end or both ends of the resistor.
