本发明可提高上面电极与端面电极之电性连接强度及第1薄膜与第2薄膜之密着力，而提供可提升强度之电阻器。形成于基板之一主面上之上面电极系由第1上面电极层及与该第1上面电极层重叠之密着层所构成，而，设于该基板之端缘且与该对上面电极电性连接之端面电极则包含有：第1薄膜，系位于该基板之端缘侧者；第2薄膜，与该第1薄膜电性连接，系由含Cu之合金薄膜所构成者；第1镀敷膜，包覆该第2薄膜，系由镀镍层所构成者；及，第2镀敷膜，系包覆该第1镀敷膜者。

A resistor has an increased reliability of a electrical connection between an upper electrode and an edge electrode, has an increased adhesivity between a first thin film and a second thin film, an thus has a high reliability. The resistor includes the first upper electrode formed on a main surface of a substrate, an adhesive layer on the first upper electrode, and the edge electrode electrically coupled with the first upper electrode. The edge electrode includes the first thin film positioned at an edge of the substrate, the second thin film being made of a thin alloy film including copper and electrically coupled with the first thin film, a first plate film being nickel-plated and covering the second thin film, and a second plate film covering the first plate film.
