PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor free from being damaged since an undesired external force given to the capacitor contained therein is suppressed when bonding a substrate or mounting a part on a printed board which contains a solid electrolytic capacitor. SOLUTION: The solid electrolytic capacitor stored in an insulative resin substrate comprises a valve metal substrate having a roughened surface on which an insulative oxide film is formed, at least an insulative oxide film, a solid high polymer electrolytic layer, and a conductive layer sequentially formed on the foil-shaped valve metal substrate. An area in the vicinity of an end of the valve metal substrate having a smooth surface is bonded to an area in the vicinity of an end of the valve metal substrate having a roughened surface such that they are electrically connected, and an area in the vicinity of an end of a conductive metal substrate is bonded to an area in the vicinity of the other end the valve metal substrate having a smooth surface such that they are electrically connected to form a positive electrode. A reinforcing material is disposed in a space in which the solid electrolytic capacitor is stored.
