A driving device (1) according to an aspect of the present invention includes first to third hydraulic cylinders (2, 3, 4), first to third hydraulic pumps (12, 13, 14), a single electric motor (15) and a power distributor (21). The first to third hydraulic pumps (12, 13, 14) supply working fluid to each of the first to third hydraulic cylinders (2, 3, 4). The electric motor (15) transmits power to each of the first to third hydraulic pumps (12, 13, 14). The power distributor (21) distributes the power of the electric motor (15) to the power required by each of the first to third hydraulic pumps (12, 13, 14). The present invention provides the driving device and a construction machine, capable of reducing the size of the driving device by suppressing an increase in a total required power required to operate a work device.
