The electrically driven winch device (1) is provided with a winch drum (2), a plurality of axial-gap electric motors (3A, 3B), and a drive shaft (4). The winch drum (2) rotates around a drum axis (AX2) in order to wind or unwind a work rope (W). The plurality of electric motors (3A, 3B) are electric motors configured to drive the winch drum (2) to rotate, and are each provided with a stator (S), and rotors (R1, R2) which rotate around a rotation axis (AX1) and are disposed at an axial distance from the stator. The drive shaft (4) is disposed coaxially with the drum axis (AX2) and serially connects the rotors (R1, R2) of the plurality of electric motors (3A, 3B) on the rotation axis (AX1).
