Electric actuator

An electric actuator comprising:

• a motor having a motor shaft that extends in an axial direction;
• a first case in which the motor is accommodated and which has a first opening that opens to one side in the axial direction;
• a second case in which a deceleration mechanism connected to the motor is accommodated and which has a second opening that opens to the other side in the axial direction;
• a rotation sensor which is accommodated in the second case and detects rotation of an output shaft of the deceleration mechanism;
• and
• a plurality of bus bars which are electrically connected to a plurality of sensor terminals that extend from the rotation sensor and are held in the second case,
• wherein the first case and the second case are fixed to each other while the first opening and the second opening face each other in the axial direction,
• wherein a plurality of connecting parts that connect the plurality of bus bars and the plurality of sensor terminals are disposed at positions shifted from each other in a circumferential direction and radially outward from the rotation sensor, and
• wherein, among the plurality of connecting parts, at least one pair of adjacent connecting parts are disposed at positions different from each other in the radial direction.
