Abstract

The head-mounted display 1 has a rear arm 2, an accommodating part 3 that is attached to the rear arm 2, a display arm 4 that is held in the accommodating part 3 so that this display arm 4 can be accommodated, a display part 5 which is attached to the tip end of the display arm 4 so that this display part 5 can pivot, and headphones 6 which are disposed on both end parts of the rear arm 2, as main parts. A flat cable 12 which supplies a power source and signals to the image display device 7 is led into the accommodating part 3 via a wiring attachment part 13, and is fastened to the accommodating part 3 by the wiring attachment part 13. In the accommodating part 3, the intermediate part of the flat cable 12 is fastened by a wiring retainer 14. Then, this flat cable 12 enters the display arm 4 from the rear end part of the display arm 4, and is further conducted to the image display device 7 inside the display part 5 via a spherical-surface coupling 10. As a result, a head-mounted display can be obtained in which there is no interference with human activity by the wiring, and in which no feeling of bother is created.
