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
