A hydraulic pump (17), an electric motor (18), an inverter (19), an oil tank (20), a heat exchanger (21), and a battery (31) are mounted on a revolving frame (5), and are covered by an exterior cover (34). Meanwhile, the revolving frame (5) is provided with a partition plate (7), and the interior of an exterior cover (34) is partitioned by this partition plate (7) into a machine room (10) for accommodating the hydraulic pump (17) and the electric motor (18) and into a battery room (11) for accommodating the battery (31). A cooling fan (30) is arranged in the machine room (10) . As this cooling fan (30) is driven, outside air is introduced into the machine room (10) through an oil tank cooling air inlet port (35) and an inverter cooling air inlet port (36) which are provided in the exterior cover (34) . This outside air cools the hydraulic pump (17), the electric motor (18), and the oil tank (20) in the machine room (10) and is exhausted to the outside of the machine room (10) through an exhaust port (38).
