PROBLEM TO BE SOLVED: To provide a vacuum insulation container incorporated superconducting magnet which improves the density of a magnetic flux that can be generated at an atmospheric side outside of a vacuum container, and is low-priced, in a superconducting bulk magnet capable of generating a magnetic field by capturing a magnetic flux by means of magnetization.SOLUTION: A surface of a superconducting bulk body 2 is formed to be fitted with a three-dimensional uneven shape 12 of a low-temperature inner cylinder bottom face shape of a vacuum insulation container 8 to dispose the superconducting bulk body 2 therein, and the superconducting bulk body 2 is disposed while being fitted to a low-temperature inner cylinder bottom face of a mass-production vacuum bottle for retaining coldness of beverage for vacuum insulation so as to minimize a gap, such that a distance from the outer cylinder bottom face at the atmospheric side of the vacuum insulation container to the surface of the superconducting bulk body 2 is shortened. In such a structure, a magnetic field available on the outer cylinder bottom face at the atmospheric side is strengthened within the magnetic field generated in the magnetized superconducting bulk body 2. 【課題】着磁により磁束を捕捉して磁場を発生できる超電導バルク磁石において、真空容器外の大気側に発生できる磁束密度が高く、安価な真空断熱容器内蔵型超電導磁石を提供する。【解決手段】超電導バルク体２の表面形状を配置する真空断熱容器８の低温内筒底面形状の３次元凹凸形状１２に嵌合する形状にし、前記真空断熱用として大量生産の飲料保冷用真空ボトルの低温内筒底面に隙間を最小にするように嵌合して、前記超電導バルク体２を配置することで、前記真空断熱容器の大気側の外筒底面から超電導バルク体２表面までの距離を短くする。この構造により、着磁された超電導バルク体２で発生する磁場内において、大気側の外筒底面で利用できる磁場が強くなる構造にしたものである。【選択図】図１
