PROBLEM TO BE SOLVED: To provide an electronic apparatus equipped with a printed circuit board having a reinforcing structure capable of improving mechanical strength at a lower cost. SOLUTION: A finger print authentication module 6 is mounted on a printed wiring board 8. When a user performs finger print authentication, the user presses its finger against a terminal 9 which is a sensor so that the finger print authentication module 6 receives a stress. By providing a reinforcing member 21 on a bottom surface 8b of the printed wiring board 8, deflection of the printed wiring board 8 is suppressed, effectively preventing disconnection or breakage because of peeling of a connection electrode 18. As the reinforcing member 21, a waste piece occurring during manufacture of the printed wiring board 8 may be used. Thanks to such configuration as a waste piece 22 constituting the reinforcing member 21 is the one occurring during manufacturing of the printed wiring board 8, the printed wiring board 8 can be reinforced with less cost.
