PROBLEM TO BE SOLVED: To suppress temperature rise around a bushing case of a container having the bushing case, while at the same time improving the long-term reliability, against temperature changes, of the container having the bushing case.SOLUTION: A container comprises: a tank 1; a tubular bushing case 2; and a closed part 9. The tank 1 and the bushing case 2 are each made of a magnetic material. The tank 1 and the bushing case 2 are connected to each other at a connection 6. The closed part 9 closes a hollow part 8 formed by a hole. The hole penetrates from one surface of at least one of only part of a circumferential area around the tank 1 which surrounds the connection 6 and only part of a circumferential area around the bushing case 2 which comes into contact with the connection 6, to the other surface facing the above-mentioned surface. The closed part 9 is made of either an insulator or a non-magnetic material. |
