Provided is a biological signal measurement device capable of suppressing an influence of noise derived from a body motion of a test subject on a biological signal measurement result. The biological signal measurement device includes a placement portion on which a test subject is placed, one or more measurement sensors configured to measure a biological signal regarding the test subject, and a sensor holder configured to hold the measurement sensors. The placement portion has a recess. At least a part of the measurement sensor is arranged inside of the recess of the placement portion. The sensor holder and the measurement sensors are arranged to be physically separated from the placement portion without coming into contact with the placement portion.

Biological signal measurement device

Provided is a measuring device that can ensure a level of a measurement signal while noise derived from the body movement of a subject is curbed. A measuring device according to the embodiments includes a first fixing body, a sensor fixing body configured to fix a sensor for detecting a biological signal, and the sensor, in which the first fixing body and the sensor fixing body have separate structures.

Measuring device

Disclosed herein is a position detection marker that includes a magnetic field source that generates magnetism, an MRI marker that can be detected by a magnetic resonance imaging method, and a holding part that fixes a relative positional relation between the magnetic field source and the MRI marker.
