To provide an electric power supply device which enables improvement of a waterproof function.SOLUTION: An electric power supply device 100 outputs electric power for charging a rechargeable battery 107 used as a power source of a movable body 106 to a power line through a relay 170 and includes: an inner box 110 which houses a substrate 150 on which the relay 170 is mounted; and an outer box 130 which houses the inner box 110. The inner box 110 has: a first body part 111 having a first opening 113; and a first lid part 112 which closes the first opening 113 and has a bottom shallower than the first body part 111. The outer box 130 has: a second body part 131 having a second opening 133; and a second lid part 132 which closes the second opening 133 and has a bottom shallower than the second body part 131. The inner box 110 is disposed at the second body part 131 so that the first body part 111 side of the inner box 110 is located at the second opening 133 side.SELECTED DRAWING: Figure 2
