To provide a power source device having a storage part suitable for storing a battery pack, in which a plurality of single battery cells are stacked, in a compressed state in a stacking direction, and to provide a manufacturing method therefor.SOLUTION: A power source device 1 comprises: a housing 10 in which a tank-shaped first accommodating part 11 having a first open face 16 is formed; and a columnar first battery pack 31 in which a plurality of single battery cells 40 are stacked. The first battery pack 31 is held in the first storage part 11 by means of a holding load acting between first and end parts 31a, 31b on both end sides in a stacking direction X and first and second internal wall parts 11a, 11b opposite in the first storage part 11. Formed in the first and second internal parts 11a, 11b are first and second groove parts 21, 22 communicating with the first open face 16, extending perpendicular to the first open face 16, and being bottomed or non-bottomed as viewed in a cross-section parallel to the stacking direction X.SELECTED DRAWING: Figure 2 【課題】複数の単電池セルが積層された組電池を積層方向に圧縮した状態で収容するのに適した収容部を有する電源装置及びその製造方法を提供すること。【解決手段】電源装置１は、第１開口面１６を有する槽状の第１収容部１１が形成された筐体１０と、複数の単電池セル４０を積層した柱状の第１組電池３１と、を備え、第１組電池３１は、積層方向Ｘの両端側の第１端部３１ａ及び第２端部３１ｂと第１収容部１１のうち対向する第１内壁部１１ａ及び第２内壁部１１ｂとの間で作用する保持荷重によって第１収容部１１内に保持されるものであって、第１及び第２内壁部１１ａ，１１ｂには、それぞれ、第１開口面１６と連通するとともにこの第１開口面１６に対し垂直に延び、かつ積層方向Ｘに対し平行な断面視では有底又は無底の凹状である第１溝部２１及び第２溝部２２が形成されている。【選択図】図２
