Thermally insulated container and magnetospinograph using same

A magnetospinograph, comprising:

• a superconducting quantum interference device to detect magnetic fields generated from a living body;
• and
• a thermally insulated container, comprising:
• an inner container;
• and
• an outer container surrounding the inner container via a void, wherein
• each of the inner container and the outer container is made of a fiber reinforced plastic prepared by impregnating a base material containing fibers with a resin,
• the inner container includes:
• a first tubular container and a second tubular container each including an internal holder to reserve a refrigerant, and
• a refrigerant inlet tube through which the refrigerant is introduced into the first tubular container,
• the outer container includes a first portion surrounding the first tubular container of the inner container and a second portion surrounding the second tubular container of the inner container, wherein the second portion of the outer container includes a predetermined area configured to receive a load of a measurement target,
• the holder of the second tubular container is in communication with the holder of the first tubular container,
• the base material in each of a predetermined area of the second tubular container and predetermined area of the second portion of the outer container contains woven fabrics,
• the base material in the predetermined area of the second portion of the outer container further contains a honeycomb sheet, the predetermined area of the second portion of the outer container having a higher rigidity from the honeycomb sheet than the areas of the outer container other than the predetermined area of the second portion of the outer container and the first portion of the outer container such that the predetermined area is configured to receive the load of the measurement target, and
• the woven fabrics are stacked on one and another surfaces of the honeycomb sheet,
• wherein,
• the superconducting quantum interference device is immersed in the refrigerant reserved in the holder of the second tubular container.
