Abstract: A multi-layered solid electrolytic capacitor is furnished with a plurality of capacitor elements 6, each having an aluminum foil 1 having an anode portion 7 and a cathode portion 8 having a dielectric oxide film 2 and a cathode layer 3 successively formed on a surface of the aluminum foil 1. The capacitor elements 6 are stacked on each other. Adjacent anode portions 7 of the capacitor elements 6 are welded to one another and adjacent cathode portions 8 are electrically connected one another by a conductive paste layer 18. An insulative resin layer 16 is disposed on a boundary between the cathode portion 8 and the anode portion 7 of at least one of the capacitor elements 6 and on an adjacent region thereto.

Abstract: Made up of a step of preparing a map expressing a correlation between solid phase percentage and viscosity of a slurry-form semi-solid metal (27) for a given metal composition; a step of setting a target viscosity corresponding to a target solid phase percentage using this map; a viscosity measuring step of measuring the viscosity of a semi-solid metal in a vessel (13) while cooling it; and a step of carrying out cooling until this viscosity reaches the target viscosity, by these steps being carried out in from the preparation of the map expressing the correlation between solid phase percentage and viscosity of the semi-solid metal to the end of cooling of the semi-solid metal the solid phase percentage of the semi-solid metal is made to match the target solid phase percentage.
