PROBLEM TO BE SOLVED: To enhance the degree of integrity between an inner member and a heat insulating member due to connection therebetween through the intermediary of a nonwoven fabric, and the adhesion theerebtween. SOLUTION: A heat insulating structure is composed of an outer member 5 which is closed therearound and defines therein a space, an inner member 6 which is located in the outer member 5, and which is closed therearound, a heat insulating member 7 located in a space between the inner peripheral surface of the outer member 5 and the other peripheral surface of the inner member 6, and a nonwoven fabric 8 provided around the outer periphery of the inner member 6, the outer periphery of the inner member 6 being connected to the heat insulating member 7 through the intermediary of the nonwoven fabric 8.
