摘要： According to this invention, a magnetic sensor (1) for measuring a magnetic field distribution of a measurement target S by using a SQUID (2) is characterized by including a storing portion (10) with an interior held in a vacuum state to store the SQUID (2), and a substantially needle-like flux introducing member (30) made of a high-permeability material to guide a magnetic flux from the measurement target (S) to the SQUID (2), wherein the flux introducing member (30) has one end (30a) located in the storing portion (10) to be away from the SQUID (2) and the other end (30b) located outside the storing portion (10).
