ABSTRACT:
The invention is directed to the electrode structure of a chip type component, such as a chip resistor, in which a plated film of low melting point metal is used as an outermost coating electrode film on the electrode portion, the layer underlying said plated film of low melting point metal on the electrode portion is formed of a metal material having a higher melting point than that of the plated film and also having good affinity with said plated film, and the electrode material comprising said plated film of low melting point metal is subjected to heat treatment at a temperature higher than the melting point thereof, so that the outermost surface of the electrode portion is coated with a remolten metal film.
