Abstract
In a monolithic electronic component in which a resistive element is incorporated by forming a resistor film on a terminal electrode, a plating film can be formed on the terminal electrode having the resistor film via electroplating in an efficient manner and with a uniform film thickness. In order to form the terminal electrode, the resistor film is disposed directly on the surface of the component body, and a conductive resin film having a relatively low volume resistivity is disposed over the resistor film. The conductive resin film is preferably adapted to have a specific resistance of less than about 1×10−4 Ω·m, on which a plating film having a uniform film thickness can be formed efficiently via electroplating.
