A compact solid electrolytic capacitor includes a capacitor element having a positive electrode and a negative electrode which are respectively connected electrically to a first lead and a second lead and a casing of a resin material surrounding the capacitor element. A low melting-point metal layer serving as a fuse, which will quickly melt under an abnormal condition, is inserted between and electrically connects the capacitor element and the second lead and an arc-extinguishing material capable of absorbing the melted metal of the low melting-point metallic material fills a throughhole through the second lead where the latter contacts the low melting-point metal layer. The low melting-point metal layer may be in the form of a flat ribbon of thickness only about 50-100 mum.
