Abstract
The resistor of the present invention comprises a substrate, a pair of upper electrode layers disposed on one surface of the substrate, and a resistor layer connected to the pair of upper electrode layers, wherein the upper electrode layer includes a first thin film layer that strongly adheres to the substrate and the resistor layer, and a second thin film layer having volume resistivity lower than the volume resistivity of the first upper electrode thin film layer. Further, the resistor of the present invention comprises a pair of side electrodes, electrically connected to the upper electrode layers, at the end portion of the substrate, and the side electrode includes a first side thin film layer and a second side thin film layer, and the material that forms the second side thin film layer has a solid solubility with the first side thin film layer.
