Abstract

PURPOSE:To ensure that a resistor is provided with a clear semi-circular shape, the width and height of the resistor can be freely changed and the resistor can be provided irrespective of the shape of a substrate, by a method wherein a resistor paste placed in a dispenser is pushed out through the tip of the dispenser to form a resistor. CONSTITUTION:A pressure is applied to the dispenser 1 from a pressure device 4 by opening a valve, whereby the resistor paste 5 contained in the dispenser 1 is pushed out through the tip of the dispenser 1. The paste 5 thus pushed out is adhered to the substrate 6 in an elongate form to form the resistor. The total sequence is controlled by a controlling circuit 11, which controls the valve 3, the pressure device 4 and a table-controlling circuit 10. The paste 5 is provided with a clear shape with a semi-circular cross-sectional shape, and the width and height of the resistor can be freely changed easily and freely by a combination of the tip diameter of the dispenser 1, the pressure applied by the pressure device 4 and the feeding velocity of the table 9.
