Two batteries (14) are fixed to a revolving frame (5) by using a battery fixing device (21). The battery fixing device (21) is formed of a battery platform (22) which is fixed to the revolving frame (5) and on which the batteries (14) are placed with a gap (S) left between them, a bending portion (23) which is provided in the battery platform (22) on the side of the back surfaces of the batteries (14) and positions the back surfaces of the batteries (14), an insertion hole (25) for hooking provided in the battery platform (22) in a position corresponding to the gap (S) between the batteries (14) lying next to each other, a grip bracket (26) disposed across upper-end corner portions of front surfaces of the batteries (14) lying next to each other, and a J bolt (29) that is placed through the gap (S) between the batteries (14) lying next to each other and connects the grip bracket (26) and the insertion hole (25) for hooking. This makes it possible to fix the two batteries (14) firmly with a small number of components.
