Abstract: An in vivo pressure measurement device includes: a light source configured to output test light; an optical fiber, to which the test light is input, at least partially including a sensor optical fiber configured to transmit the test light with a loss of 0.3 dB/m or more; and a light receiving unit configured to receive the test light transmitted through the sensor optical fiber. The in vivo pressure measurement device is configured to measure pressure in a living body acting on the sensor optical fiber based on intensity of the test light received at the light receiving unit.
