1. A biomagnetism measuring device, comprising:
a plurality of magnetic sensors configured for measuring biomagnetism simultaneously; and
a holder portion,
wherein the plurality of magnetic sensors is held by the holder portion so as to have different measuring directions,
wherein the plurality of magnetic sensors is provided at the holder portion so as to be capable of measuring biomagnetism of multiple sites simultaneously, and
wherein the plurality of magnetic sensors comprises a sensor that detects the biomagnetism in a thermal environment commensurate with normal temperature with no need for cooling, and
wherein the holder portion comprises:
a first holder portion in which the plurality of magnetic sensors is arranged two-dimensionally at positions in a (x-y) coordinate substantially parallel to a body surface of a living organism,
a second holder portion in which the plurality of magnetic sensors is arranged two-dimensionally at positions in a coordinate different from the (x-y) coordinate,
a third holder portion in which the plurality of magnetic sensors is arranged two-dimensionally,
an open/close mechanism that enables the third holder portion to open and close with respect to the first holder portion or the second holder portion, and
a moving mechanism that enables the third holder portion to move toward the first holder portion or the second holder portion.
