To improve productivity by reducing cost in production of a power storage module.SOLUTION: An insert die 70 placed in an injection molding die M in production of a power storage module 4 includes: multiple plates 51A, 51B placed side-by-side in a lamination direction D1 of a laminate 11, and inserted into multiple internal spaces V of the laminate 11; an inter-plate member 52 placed between the plates 51A, 51B; and a nest block 50 having a first outer member 53 placed on the opposite side to the inter-plate member 52 of the plate 51A, and a second outer member 54 placed on the opposite side to the inter-plate member 52 of the plate 51B, where the nest block 50 is integrated when the first outer member 53 and the second outer member 54 sandwich and hold the multiple plates 51A, 51B with the inter-plate member 52. The individual plates 51A, 51B can be replaced upon breakdown of the plates 51A, 51B, and productivity can be improved by reducing cost in production of the power storage module 4.SELECTED DRAWING: Figure 6 【課題】蓄電モジュールの製造でコストを削減して生産性を向上させる。【解決手段】蓄電モジュール４の製造で射出成形用金型Ｍに配置される入れ子型７０は、積層体１１の積層方向Ｄ１に並んで配置され、積層体１１の複数の内部空間Ｖに挿入される複数のプレート５１Ａ，５１Ｂと、プレート５１Ａ，５１Ｂの間に配置されるプレート間部材５２と、プレート５１Ａのプレート間部材５２とは反対側に配置される第１外側部材５３と、プレート５１Ｂのプレート間部材５２とは反対側に配置される第２外側部材５４とを有する入れ子ブロック５０を備え、入れ子ブロック５０は、第１外側部材５３と第２外側部材５４とがプレート間部材５２とともに複数のプレート５１Ａ，５１Ｂを挟み込み保持することで一体化される。プレート５１Ａ，５１Ｂの損傷時に個々のプレート５１Ａ，５１Ｂの交換が可能であり、蓄電モジュール４の製造でコストを削減して生産性を向上できる。【選択図】図６
