A power transmission device that includes an electromagnetic wave-shielding wall partitioning a space and a space, a rotating shaft penetrating through the electromagnetic wave-shielding wall to transmit rotating drive force, and a bearing supporting the rotating shaft. The rotating shaft includes a first shaft member supported by the bearing, a shaft joint part provided on an end of the first shaft member, and a second shaft member rotating together with the first shaft member. The first shaft member and the second shaft member are formed of a conductive material, and the shaft joint part has an insulating part formed of an insulating material. An outer race component part of the bearing has an annular close-contact surface formed of a conductive material.
