Abstract
An electronic device according to the present invention includes an infrared ray absorbing section 12, which comes to have an increased temperature when irradiated with an incident infrared ray, and at least one heat sensing section 13, of which a physical property varies with the variation in temperature that has been caused due to the heat generated by the infrared ray absorbing section 12. The relative positions of the heat sensing section 13 and the infrared ray absorbing section 12 can be changed so as to switch their states from a first state, in which the infrared ray absorbing section 12 and the heat sensing section 13 are in contact with each other, into a second state, in which the infrared ray absorbing section 12 and the heat sensing section 13 are out of contact with each other, and vice versa.
