Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problem in a tank for cryogenic fluid with a metal inner shell and a composite material outer shell, that, when the cryogenic fluid is poured therein, the inner shell and the outer shell having different linear expansion coefficients are deformed at an opening portion in opposite directions and excessive stress is generated at both joint ends to possibly cause the separation. SOLUTION: In the tank A for cryogenic fluid, an opening portion H is provided at least whose peripheral part consists of the metal inner shell 1 and the composite material outer shell 2. On the peripheral part of the opening portion H, a bolt 4 is provided as a fixing means for constraining the inner shell 1 and the outer shell 2 with each other. When the inner shell 1 and the outer shell 2 may be deformed at the opening portion H in the opposite directions, stress is less generated at both joint ends to prevent the separation.
