PROBLEM TO BE SOLVED: To avoid a decline in image brightness or deterioration in the quality of parts of an HMD (head-mounted display), by efficiently making the heat, generated by a light source 11, lead to the outside of a casing 3 and dissipate efficiently. SOLUTION: An image display device of an HMD has a light source 11 that has an LED and a heat-absorbing member 34 inside a casing 3. The light source 11 is soldered to a land portion of the FPC 3. The heat-absorbing member 34 is placed on a side opposite to the surface where the light source 11 of the FPC 31 is mounted. The heat-absorbing member 34 is connected to a shielded cable 62 of a cable 6 by soldering 35. Since the land portion has a fixed area in the FPC 31 and the heat-absorbing member 34 has a fixed area with respect to the FPC 31, the heat generated by the light source 11 is dissipated efficiently from the surface of the land portion of the FPC 31, and is then, via an insulating layer of the FPC 31, absorbed efficiently via the surface of the heat-absorbing member 34, and is thereafter led out of the casing 3 and transferred to the outside via the shielded cable 62.
