To provide an output device which does not cause a user to have an unpleasant feeling by the rise of temperature in a holding part for storing electric circuits.

A head mount display includes: ear pads 1, 2 for pressurizing both ears from right and left thereby fixing the head mount display onto a head part. The respective ear pads 1, 2 are fixed to the holding parts 7, 8 via universal hinges 5, 6. The right and left holding parts 7, 8 are freely slidably inserted to the inner part of a head band 9 and connected by the head band 9. The electric circuits 13 are attached to the inner part of the case of the holding part 8. The universal hinge 6 is freely rotatable, while receiving the elastic force of a wire spring, but is made of a material with low thermal conductivity, thereby allowing heat generated from the electric circuits 13 to be hardly transmitted to the ear pad 2 and suppressing the rise of temperature in the ear pad 2 to be ignorable.
