Abstract: There is provided a resistor in which a first resistive part of a resistive element that electrically conducts between a pair of electrodes formed on either end of an insulating substrate has a meandering pattern meandering on the substrate surface and a swelling pattern that has a form in which a part of the meandering pattern swells out from the stroke width of the meandering pattern, a second resistive part that is electrically connected in series to the first resistive part is shorter than the entire length of the first resistive part, and has a wider width than the stroke width of the meandering pattern, and a trimming groove is formed in at least either the swelling pattern or the second resistive part. This can improve resistance accuracy and provide a high voltage resistor with high withstand voltage property.
