PROBLEM TO BE SOLVED: To provide a power supply device capable of preventing warming of a blower and enhancing a cooling effect of a battery, and a working machine including the same.SOLUTION: A power supply device 1 includes: a plurality of batteries 2; an accommodation body 4 which constitutes an accommodation chamber 13 for accommodating the batteries and has an intake part 17A for taking air into the accommodation chamber and a sending-out part 16 for sending out air; a casing 3 for accommodating the accommodating body in an internal space, which is surrounded by a first transverse wall surface 31 provided on the first side of the batteries and facing the intake part and a second transverse wall surface 33 provided on the side opposite to the first side of the batteries and opposed to the first transverse wall surface; and a blower 5 disposed between the second transverse wall surface and the battery for blowing air taken in from the intake part. At least a part of the sending-out part is disposed so as to be shifted in an orthogonal direction orthogonal to the arranging direction so as not to overlap with the blower in the arrangement direction of the blower and the battery.SELECTED DRAWING: Figure 2

    【課題】送風機が温められることを防ぎ、電池の冷却効果を高めることができる電源装置及びこの電源装置を備えた作業機を提供すること。【解決手段】電源装置1は、複数の電池2と、電池を収容する収容室13を構成し且つ当該収容室内に空気を取り入れる取入部17Aと空気を送り出す送出部16とを有する収容体4と、電池の第1の側に設けられて取入部と対向する第1横壁面31と、電池の第1の側と反対側に設けられて第1横壁面と対向する第2横壁面33とを含む複数の壁面により囲まれる内部空間を構成し、当該内部空間に収容体を格納する筐体3と、第2横壁面と電池との間に配置されて、取入部から取り入れられる空気を吹き出す送風機5と、を備え、送出部の少なくとも一部が、送風機と電池との並び方向において送風機と重ならないように、並び方向に直交する直交方向にずれて配置されている。【選択図】図2
