A battery module of the invention includes: a battery (1) having a positive electrode terminal (11), a negative electrode terminal (12), and a battery case (10); a cap (3) having holes (31, 32) respectively corresponding to the positive electrode terminal (11) and the negative electrode terminal (12) and formed of an insulating member covering an end of the battery (1); and a protection portion to block at least one of the holes. When the cap (3) is pressed and inserted into the end of the battery up to a predetermined amount or more, the positive electrode terminal (11) or the negative electrode terminal (12) protrudes from the cap (3) through the protection portion. |
