PROBLEM TO BE SOLVED: To solve the difficulty of prior art that conditions of degrading of parts used for a power supply circuit in a temperature range used become severe in view of the rise of ambient temperature of the power supply circuit owing to the heating of an electronic circuit to result in the cost up and the designed life shortened. SOLUTION: In an electronic apparatus which includes an electronic circuit and a power supply circuit, and further a case body 1 mountable on a wall surface, when the case body 1 is mounted on a wall surface, the electronic circuit and the power supply circuit 10 are arranged in parallel horizontally in the case body 1. Hereby, an effect of the rise of ambient temperature of the power supply circuit 10 due to heating of any transistor and the like constituting the electronic circuit is suppressed.
