To provide an electrically-driven work machine equipped with an electric drive device capable of improving convenience at the time when charging a power storage element with electric power from an external power source such as a commercial power system, and simplifying a circuit configuration than before.

An electrically-driven work machine 100 is equipped with an electric drive device 10 containing a plurality of inverters 11,... for respectively driving a plurality of motors M,... with the same DC voltage supplied from a power storage element BT. The electrically-driven work machine 100 is equipped with first opening/closing means SWa which allows electrical conduction or shielding between a first leg group G1 and a connection leg group Gn. The electrically-driven work machine 100 further includes first connection terminals T1 and T2 for connecting a first inductor L1 between the middle point of leg LG1 of the first leg group G1 and the middle point of leg LG6 of the second leg group G2, as well as second connection terminals T3 and T4 for connecting an external power supply PW by way of a second inductor L2 between the middle point of leg LG7 of a third leg group G3 and the middle point of leg LG12 of a fourth leg group G4.
