Abstract
A biomagnetism measurement device includes a tubular body, an inflatable portion inflatable upon supply of gas, and a magnetic sensor portion that detects a magnetic field from outside the tubular body. The inflatable portion is located at a required region of the tubular body, and the magnetic sensor portion is fixed to an inner wall of the inflatable portion. The tubular body and the inflatable portion include the same material, and the wall thickness of the inflatable portion is thinner than that of the tubular body.
