Abstract

A chip componentcomprises: an insulating substrateon which a resistorserving as a functional element is formed; a pair of internal electrodes (front electrodes, end surface electrodes, and back electrodes) that is formed to cover both end portions of the insulating substrateand connected to the resistor; a barrier layerthat is formed on a surface of each of the internal electrodes and mainly composed of nickel; and an external connection layerthat is formed on a surface of the barrier layerand mainly composed of tin, and the barrier layeris composed of alloy plating (Ni—P) including nickel and phosphorus, which is formed by electrolytic plating, and a content rate of phosphorus in the alloy plating of an inner region is made different from that of an outer region so that at least the inner region of the barrier layerhas magnetic properties.
