Patent ID: 7999652

Claim:
A thick film resistor, comprising: an insulating substrate; a pair of electrode conductors that are disposed on the insulating substrate; and a winding resistor that is disposed on the insulating substrate between the pair of electrode conductors, wherein the winding resistor is formed by periodically repeating a predetermined pattern having a predetermined film thickness and a line width, and has a shape to satisfy the relationship of the following Expression 1 when one point on a central line of the resistor is represented by X A , an intersection point where a straight line virtually drawn from the point X A in a direction parallel to a straight line that connects the pair of electrode conductors to each other by the shortest distance intersects the central line of the resistor after the point X A is represented by X B , and the next intersection point where the straight line intersects the central line of the resistor after the intersection point X B is represented by X C , a length of a path on the central line of the resistor from the point X A to the point X B is represented by l AB , a length of a path on the central line of the resistor from the point X B to the point X C is represented by l BC , a shortest distance from the point X A to the point X B is represented by D 1 , and a shortest distance from the point X B to the point X C is represented by D 2 , l AB /D 1 =l BC /D 2 .
