To provide an integrated system diving apparatus simple in structure, low in cost, high in safety, and to be combined freely according to purposes.

An ear plug is formed so that the entry of water and the pain of an ear can be prevented by a soft membrane and sound can be transmitted by the membrane, and also so as to be used as an earphone. A tape is adopted to easily and surely detach and attach a hydroscope. A valve is utilized as a snorkel for waterproofness and dustproofness and for discharging entered water. An underwater speaker is used to emit voice into underwater and the shape thereof is improved. When diving is performed for a short time, even if a special installation is absent, the diving can be performed for approx. 20 to 30 minutes with a simple installation by manufacturing an easily used soft container like a life jacket and removing condensed oxygen and carbon dioxide to reproduce respiratory air. When the diving is peprformed for a long time, hydrogen and oxygen are produced by using seawater for respiration. For power supply, a special seawater electricity is used to provide various power supplies. When the container is not used for diving, it is used as the life jacket.
