Abstract: An electric actuator includes a motor portion, a circuit board, a speed reduction mechanism, a busbar holder that holds a busbar, and a housing. The housing has a motor case and a compartmental wall. The compartmental wall has a through-hole which penetrates the compartmental wall in an axial direction. The busbar holder has a base portion and a projecting portion which projects from the base portion in the axial direction and is disposed in the through-hole. An end portion of the busbar at one side projects from the busbar holder toward one side in the axial direction and is connected to the circuit board, and an end portion of the busbar at the other side projects into the through-hole from a side surface of the projecting portion of the busbar holder and is connected to a coil of a stator.
