To provide a power source device which can prevent an air permeable waterproof part from being damaged even when high temperature gas blows out from a battery module.SOLUTION: A power source device comprises: battery modules 10, 11; a cover which stores the battery modules 10, 11 and is formed with an opening 45; a lid part 50 which is provided on the outer surface of the cover so as to close the opening 45; a plug which is provided in the cover; and a reinforcement member 45 which is provided on the inner surface of the cover and is provided along the opening edge part of the opening 45. The lid part 50 includes an air permeable waterproof part 81 which is provided between the inside of the cover and the outside. The plug is provided detachably through the opening 45 in such a state that the lid part 50 is detached. The reinforcement member 45 comprises: a reinforcement plate 57 which is formed so as to protrude in the protrusion direction being apart from the inner surface from the inner surface side of the cover; and a protrusion plate 56 which protrudes in the protrusion direction and is provided on the air permeable waterproof part 81 side with respect to the reinforcement plate 57. The length of the protrusion plate 56 is longer than the length of the reinforcement plate 57 in the protrusion direction.SELECTED DRAWING: Figure 1 【課題】バッテリモジュールから高温ガスが噴出したとしても、通気防水部が損傷することを抑制することができる電源装置を提供する。【解決手段】電源装置は、バッテリモジュール１０，１１と、バッテリモジュール１０，１１を内部に収容すると共に、開口部４５が形成されたカバーと、開口部４５を閉塞するように、カバーの外表面に設けられた蓋部５０と、カバー内に設けられたプラグと、カバーの内表面に設けられると共に、開口部４５の開口縁部に沿って設けられた補強部材４５とを備え、蓋部５０は、カバー内と外部との間に設けられた通気防水部８１を含み、プラグは、蓋部５０を取り外した状態で開口部４５を通して取り外し可能に設けられており、補強部材４５は、カバーの内表面側から内表面から離れる張出方向に張り出すように形成された補強板５７と、張出方向に張り出すと共に補強板５７よりも通気防水部８１側に設けられた張出板５６とを含み、張出方向において、張出板５６の長さは、補強板５７の長さよりも長い。【選択図】図１
