[Problem] In order to mount a pair of electric motor-equipped axle drive devices, each with an integrated inverter, on a work vehicle, it is necessary to have a compact configuration to avoid interference with other vehicle parts. [Solution] The electric motor-equipped axle drive device includes: an axle case that accommodates an input shaft that receives power from the electric motor, a single axle that is substantially parallel to the input shaft, and a gear mechanism that operatively connects the input shaft and the single axle, and the axle case having a section that supports the input shaft and a section that supports the single axle; a motor case of the electric motor that is provided on one side of the input shaft support section; and an inverter that controls the electric motor so as to be capable of supplying electric power, and which includes an inverter case that accommodates a circuit board of the inverter. The inverter case has a base end section that is attached to an end surface or an outer peripheral surface of the motor case, and a terminal section on the opposite side to the base end section. The terminal section is arranged in a space facing one side of the axle support section and is a space on the opposite side to the side on which the axle protrudes.
