PROBLEM TO BE SOLVED: To make a test piece possible to, properly adsorb tritium by making the test piece possible to be impregnated with tritium at a high temperature, thereby preventing tritium from leaking outside a system. SOLUTION: This device has a test water pot 3 where pure water 14 containing tritium and hydrogen and are introduced via an introducing pipe 7a and the pure water 14 is deaerated, a test pot 1 where the deaerated pure water 14 is supplied from the test water pot 3 via a piping 13, a test piece 2 is housed inside, internal temperature thereof is maintained at a specific value by a heater 12, and tritium is generated by corrosion reaction, and a floating cylinder 4 which is connected to the piping 13 and maintains the pressure in the test pot 1 at a specific value, thus preventing a large amount of tritium being impregnated at the test piece 2 from being generated as in the case of conventional electrolysis, avoiding a risk where tritium from leaking outside a system since the pressure in the test pot 1 is adjusted to a specific value, and the test piece 2 it is made possible to properly adsorb tritium since the deaerated pure water 14 is used.
