A resistor 2 is provided between the main turns 1 and 1 so as to partially cover the wiring and the turfs 1 and 1. When finely adjusting the resistance value of a thick film resistor element having such a structure, for example, laser This is done by trimming the resistor 2 to the right to provide a notch 3.

印で示す方向にオープンに至るという欠点があった。However, in the thick film resistive element having the above-described structure, as shown in FIG. 2, the current is greatest at the point closest to the notch 3, causing current concentration. Therefore, each time a large voltage or surge voltage is applied to the resistor 2, the resistor 2 burns out in the trimming direction from the notch 3, and eventually opens in the direction shown by the arrow in FIG. 3, which is a drawback.

抗素子を提供することを目的とするものである。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a thick film resistive element that prevents the resistance between wiring patterns from becoming completely open.

ある。In the present invention, by providing a separating portion in a direction substantially perpendicular to the direction in which the resistor is to be trimmed, the resistor connected between the wiring and the pattern on the insulating substrate can be used to reduce large voltages and surge voltages after trimming. This is to minimize the resistance portion that burns out due to application of voltage, and prevent the resistance from becoming open.

Since the separating portion 13 is provided in the resistor 12 between the first and second turns 11 and 11 in a direction perpendicular to the trimming direction, the resistance value f141 is removed by applying a large voltage after trimming the resistor region 141'k) to be trimmed. If the burnout breaks in the longitudinal direction of the notch 15, the breakage is stopped at the separation part 13, and its influence extends to the depth of the resistance area 14 that is not trimmed.
You can prevent the effects from spreading. Therefore, wiring pattern 1
Although the resistance value between 1 and 11 fluctuates somewhat, fatal defects can be avoided.
