PROBLEM TO BE SOLVED: To provide a bathometer having high reliability without being broken even under a high water pressure. SOLUTION: The bathometer is provided by installing an air-accumulating chamber at the endmost part 13a of an air chamber 13 of the bathometer and making it have a communicating state with the air chamber, also installing an opened-up window 15 at its body, and linking the air-accumulating chamber with the body to expose the air-accumulating chamber under water. As the flexible plate 16a of the air-accumulating chamber, a material having a form such as a disk or bellows and rich in flexibility is suitable. Additionally, to the flexible plate 16a, reserve tension is given. The volume of the air-accumulating chamber is made to have a minimum value by making the chamber always closely stick to a base stand with the restoring force of the material itself.
