1. A method of manufacturing an aluminum electrolytic capacitor device, comprising the steps of:

  • molding a resin casing including an outer wall surrounding an interior space and having an open end opening to the interior space, integrally with a pair of terminals perforating the outer wall so as to extend from the exterior of the casing into the interior space;

    inserting an aluminum electrolytic capacitor element having an anode aluminum foil and a cathode aluminum foil into the interior space;

    electrically connecting the anode aluminum foil to one of the pair of terminals and electrically connecting the cathode aluminum foil to the other of the pair of terminals;

    providing an electrolyte within the resin casing; and

    closing the interior space by covering the open end of the casing with a resin lidsaid step of molding a resin casing including the steps of supporting a first end of each terminal in abuttment with a bearing surface of a core of a stationary template, mounting a movable template over the stationary template with a second end of each terminal bent with respect to the first end clamped between the stationary and movable templates with a perforating portion of each terminal extending through an open space in the shape of the casing to be formed between the stationary template and movable template, and injecting a resin material into the open space so as to form the casing with the terminals fixed therein at their respective perforating portions.
