Abstract

A chip resistor has a substrate, a first connection electrode and a second connection electrode that are formed on the substrate, and a resistor network that is formed on the substrate and that has ends one of which is connected to the first connection electrode and the other one of which is connected to the second connection electrode. The resistor network is provided with a resistive circuit. The resistive circuit has a resistive element film line that is provided along inner wall surfaces of trenches. The resistive element film line extending along the inner wall surfaces of the trenches is long and has a high resistivity as a unit resistive element.
