Zusammenfassung:PROBLEM TO BE SOLVED: To provide a sealed article with which leakage test can easily be conducted, its leakage testing method and its manufacturing method. SOLUTION: This article is designed so as to comprise a container 10 containing water 11, an inlet 20 formed on the container 10, an inner sealing section 30 sealing the inlet 20, an outer sealing section 50 which further seals the inlet 20 outside the inner sealing section 30, and a sealed space area 40 formed between the inner sealing section 30 and the outer sealing section 50 to enclose tracer gas for leak check of the outer sealing section 50.
