A magnetic measuring apparatus includes an inclination gantry including a mount surface and an inclined surface that is inclined with respect to the mount surface, a cryostat disposed on the inclined surface, a cryocooling system connected to the cryostat, a sensor tube connected to the cryostat and including a curved surface that does not curve in a predetermined direction and curves in a direction orthogonal to the predetermined direction such that a center of the curved surface protrudes with respect to side edges of the curved surface, and a magnetic sensor that measures biomagnetism and is housed in the sensor tube such that a sensor surface of the magnetic sensor faces the curved surface. The sensor surface is inclined with respect to the mount surface in a direction that is the same as a direction in which the inclined surface is inclined.
