Fabrication method for laminated-type secondary battery

A method for fabricating a laminate-type secondary battery, comprising:

• setting a laminated-film exterior package member as an insert in a mold, the laminated-film exterior package member accommodating cell elements;
• and
• integrally forming a bead-shaped edge protector in a peripheral edge of the laminated-film exterior package member by molding a hot melt resin material such that the hot melt resin material surrounds an end edge of the laminated-film exterior package member and both opposite surfaces of the laminated-film exterior package member in a vicinity of the end edge,
• wherein a compressed air is introduced between a mold surface defining a cavity of the mold and a surface of a hot melt resin layer formed of the hot melt resin material after starting to fill or inject the hot melt resin material into the cavity and before a temperature of the hot melt resin material becomes equal to or lower than a softening point thereof,
• wherein introduction of the compressed air is carried out by blowing the compressed air in a same direction as a direction in which a plurality of ejector pins are projected from a part of the mold surface defining the cavity, and
• wherein the direction in which the compressed air is blown is aligned with a direction in which the edge protector formed of the hot melt resin material is pressed onto one of the opposite surfaces of the laminated-film exterior package member or another of the opposite surfaces thereof.
