ABSTRACT:
A capacitor element for use in a solid electrolytic capacitor is formed by sintering metallic powder inside a porous body to produce a chip member having one end of an anode wire buried inside the chip member. The chip member and the anode wire are welded together by laser irradiation within an atmosphere of an inactive gas or an oxidation-reduction gas to form one or more welded portions where the anode wire emerges from the chip member such that the anode wire is made stronger against bending.
