PROBLEM TO BE SOLVED: To suppress occurrence of distortion when molding a frame body.SOLUTION: A method for manufacturing battery pack includes: a step of combining a framework 1 with a slide die having slidably insertable and extractable first molds 2A, 2B to be inserted into an inner face of the framework 1, one pair of slidably insertable and extractable first holding pins 4B, 4A disposed on the right and left of the first molds 2B, 2A, and a slidably insertable and extractable second holding pin 6 disposed on the center between the first molds 2A and 2B, and injection molding a resin for molding a frame body; a step of extracting the first molds 2A, 2B from the framework 1 while leaving the second holding pin 6 after hardening the frame body; a step of sliding the one pair of first holding pins 4A, 4B in mutually approaching directions on both side faces of the tip of the second holding pin 6 while holding a part of the frame body, and extracting them from the framework 1; and a step of extracting the second holding pin 6 from the frame body 1 and removing the frame body from the framework 1. |
