PROBLEM TO BE SOLVED: To provide an electronic apparatus provided with a push-button unit on which a plurality of push-buttons are arranged, prevented from erroneous mounting of the push-button unit which can be easily mounted. SOLUTION: An interphone 1 as an electronic apparatus comprises the push-button unit 2 on which a plurality of push-buttons 2a to 2f are symmetrically arranged in vertical and lateral directions; a circuit board 9 on which switches switched by a pushing operation of the push-buttons 2a to 2f of the push-button unit 2 are mounted; and a front cover 11 housing the push-button unit and the circuit board 9. The push-button unit 2 has a supporting part 21 for supporting the push-buttons 2a to 2f in addition to the push-buttons 2a to 2f, and the supporting part 22 is arranged asymmetrical against the arrangement of the push-buttons. The front cover 11 has openings 15a to 15f where top end parts of the push-buttons 2a to 2f are exposed, and positioning ribs 16a, 16b, to which the supporting part 21 is made to contact and the push-button unit 2 is positioned.
