To provide a water pressure resistant shell body, an underwater apparatus and a submarine capable of enduring great hydraulic pressure, while being light weight.SOLUTION: Thin wall units 32a with thin wall thickness and thick wall units 32b with thick wall thickness are arranged alternately in a longitudinal direction X of water resistant shell bodies 30A, 30B, 30C in the water resistant shell bodies 30A, 30B, 30C to be submerged having the longitudinal direction X. Furthermore, the water pressure resistant bodies are composed including an intermediate member 32 of a rotary body shape, the inside of the intermediate member 32 is composed of a continuous surface without any irregularities, and the outside of the intermediate member 32 is composed of a surface with irregularities. Alternatively, the outside of the intermediate member 32 is a continuous surface without irregularities and the inside of the intermediate member 32 is composed of a surface with irregularities.SELECTED DRAWING: Figure 1
