PROBLEM TO BE SOLVED: To solve a problem wherein a measuring function is not operated sufficiently not to allow an accurate test, because water intrudes into an inside of a rebound hammer when used under water, as the execution of the test under water is not taken into consideration in a conventional method. SOLUTION: This nondestructive testing method for an underwater concrete structure uses the rebound hammer built in a pressure-resisting vessel preventing intrusion of water and an influence of water pressure, and has performance having all the functions of the rebound hammer used as same as those on land.
