Superconducting quantum interference device (SQUID) sensor module and a magnetoencephalography (MEG) measuring apparatus. The SQUID sensor module includes a fixed block having one end fixed to the sensor-mounted helmet, a bobbin having one end combined with the other end of the fixed block and having a groove in which a pick-up coil is wound, a bobbin fixing or attachment structure or material fixed to the other end of the fixed block via a through-hole formed in the center of the bobbin, a SQUID printed circuit board (PCB) disposed one an upper side surface of the bobbin and including a SQUID sensor, and a signal line connection PCB inserted into an outer circumferential surface of the fixed block and adapted to transmit a signal detected in the SQUID sensor to an external circuit.
