Abstract: Disclosed is a method of producing a chip-type solid-electrolyte capacitor, in which the surface of a sheathing resin layer formed on an anode body is roughened by forming an irregularity thereon, and plated metal layers are formed on the surface thus roughened for an anode and cathode use. The metal layers are strongly adhered on the roughened surface. The surface-irregularity of the sheathing resin layer is produced by blasting hard particle material made of, for example, alumina or glass using a sandblast machine, or by irradiating a laser beam such as the YAG laser beam or the like.
