PROBLEM TO BE SOLVED: To provide a battery pack capable of reliably holding unit cells even in a case of proceeding the thinness of a package and suppressing an increase in cost while having high appearance quality.SOLUTION: The battery pack has unit cells 101 to 106, .., which are two-dimensionally arranged flat triangles, battery holders for holding a gap between the unit cells 101 to 106, .., and an outer case for surrounding them. The battery holder is an aggregate of four holder members 111 to 114, each of the holder members 111 to 114 is provided with eaves 1121, 1122, .. at each arm of a frame body, and the unit cells 101 to 106, .. are reliably held by bringing an inner surface of the arm and inner surfaces of the eaves 1121, 1122, .. into contact with side faces of the unit cells 101 to 106, ... |
