Patent ID: 8310425

Claim:
A resistance dividing circuit comprising: a resistive element formed in an area between a first line segment and a second line segment which are set on a substrate and arranged in parallel to each other, thereby the resistive element is sheet-shaped along the first and second line segments; and a tap portion connected to and attached on a side wall of the sheet-shaped resistive element and located at a predetermined position at the first line segment side, wherein a cutout, being an area in which the resistive element does not exist, is formed in a place corresponding to the predetermined position in a lengthwise direction of the resistive element, wherein the resistive element has substantially a fixed width, which is equivalent to an interval between the first and second line segments, everywhere except at the predetermined position where a width of the resistive element is effectively more narrow than elsewhere, wherein a part of the cutout and a part of the resistive element are arranged in a lateral position, and wherein the tap portion has a taper having a width that becomes wider towards the resistive element in a lengthwise direction.
