Provided is a waterproof box capable of increasing the amount of water drained from a double wall without reducing the rigidity of a body case. A waterproof box (1) is provided with a body case (3) and an upper cover (2) attached to the body case (3) so as to cover the opening (30a) of the body case (3). The peripheral wall (39) of the body case (3) has a double-wall structure including an outer wall (31) and an inner wall (32). Liquid entering from a seam between the upper cover (2) and the outer wall (31) passes between the outer wall (31) and the inner wall (32) and runs outside the body case (3). A wide portion (6) and a narrow portion (7) which have mutually different distances between the outer wall (31) and the inner wall (32) are formed in the body case (3). Further, the inner wall (32) has connection parts (8) which are bent outward from the ends of the wide portion (6) and inward from the ends of the narrow portion (7). |
