PROBLEM TO BE SOLVED: To provide an electric actuator in which operation of connecting a conductive member to an electric motor can be easily performed, and sealing between the conductive member and a case is not necessary.SOLUTION: The electric actuator comprises a drive unit having an electric motor 7, and a motion conversion mechanism unit that converts rotary motion of the drive unit to linear motion. The motion conversion mechanism unit comprises a nut that rotates in response to the rotary motion of the drive unit, and a screw shaft that is disposed on the inner circumference of the nut and that linearly moves in association with the rotation of the nut. In the electric actuator, a case 10 and a conductive member 19 formed integrally with the case 10 are provided. The conductive member 19 has an insertion portion 194. A motor terminal 7c of the electric motor 7 is inserted in the insertion portion 194 so as to be conductively connected.SELECTED DRAWING: Figure 10
