Abstract
A resistor having reliability in electrical connection between an upper surface electrode and a side face electrode, and in bonding strength between a first thin film and a second thin film is provided. The resistor includes upper surface electrodes formed on a main surface a substrate and side face electrodes disposed to side faces of the substrate and connected electrically to the pair of upper surface electrodes, respectively. The upper surface electrode includes a first upper surface electrode layer and a bonding layer overlying the first upper surface electrode layer. The side face electrode includes a first thin film disposed to a side face of the substrate, a second thin film composed of copper-base alloy film and connected electrically to the first thin film, a first plating film formed by nickel plating for covering the second thin film, and a second plating film covering the first plating film.
