Abstract: In a support member, m×n (n is an integer equal to or larger than 4) cylindrical storage battery cells are arranged in a trefoil formation structure comprised of m (m is an integer equal to or larger than 4) tiers along a first direction. Along a second direction in the support member, n storage battery cells are arranged in a first tier, n+1 storage battery cells are arranged in a second tier, n storage battery cells are arranged in an m−1th tier, and n−1 storage battery cells are arranged in a m-th tier. The n storage battery cells in the first tier are arranged inward of the n+1 storage battery cells in the second tier in the second direction, and the n−1 storage battery cells in the m-th tier are arranged inward of the n storage battery cells in the m-lth tier in the second direction.
