A head-mounted display has a rear arm, an accommodating part attached to the rear arm, a display arm that is held in the accommodating part, a display part which is pivotably attached to a tip end of the display arm, and headphones which are disposed on both end parts of the rear arm. A flat cable which supplies a power source and signals to the image display device is led into the accommodating part via a wiring attachment part, and is fastened to the accommodating part by the wiring attachment part. In the accommodating part, the intermediate part of the flat cable is fastened by a wiring retainer. The flat cable enters the display arm from the rear end part of the display arm, and is further conducted to the image display device inside the display part via a spherical-surface coupling.
