Abstract: A probe unit is a probe unit used to measure hemoglobin dynamics inside a subject, and the probe unit includes a main body having flexibility, a first probe attached to the main body and having a first face from which a first light emitting portion for irradiating the subject with light is exposed, a second probe attached to the main body to face the first probe and having a second face from which a first light incidence portion for detecting light propagated inside the subject is exposed, a first light shielding member having light shielding properties, containing an elastic material, and attached to the first face to surround an emission axis of the first light emitting portion, and a second light shielding member having light shielding properties, containing an elastic material, and attached to the second face to surround an incidence axis of the first light incidence portion.
