Abstract

A mold die includes a resin injection gate through which fluid resin serving as mold resin is injected toward a cavity, a resin reservoir to store the fluid resin flowing through the cavity, and a resin reservoir gate. The resin reservoir is provided on the side opposite to the side on which the resin injection gate is arranged with the cavity interposed. The resin reservoir gate communicatively connects the cavity and the resin reservoir. The opening cross-sectional area of the resin reservoir gate is smaller than the opening cross-sectional area of the resin injection gate.
