PROBLEM TO BE SOLVED: To provide waterproof structure, in which the waterproofing works of an external floor can be conducted easily and can also be executed accurately even at the outside angle of the external floor particularly and which has excellent workability and watertightness. SOLUTION: The waterproof structure is constituted in such a manner that a water-resistant steel plate 2 with a flat section 21 and upstanding sections 22 on the two sides is arranged at the outside angle through a heat-insulating material 1, each upstanding section 22 is fixed onto retaining walls Q having two surfaces forming the outside angle and connected by a reinforcing member 7, waterproof sheets 3 made of a soft resin are installed up to the upper edge sections of each retaining wall Q along each upstanding section 22 of the water- resistant steel plate 2, an outside angle cover 81 integrally formed in a watertight manner so as to be positioned along the ridge angle section of the outside angle and made of a soft resin is fixed at the ridge angle section of the outside angle through a mounting member 82 stuck on the rear of the cover and an edge section on the outside of the outside angle cover 81 is stuck so as to cover edge sections on the outside angle sides of each waterproof sheet 3.
