Abstract
A first holding member and a second holding member are arranged so as to sandwich a measurement site of a measurement subject, and are capable of clamping the measurement site. A light beam emitted from a light emitting unit is guided to the first holding member by an optical fiber, passes through an optical system, is reflected by a reflection unit, and is then incident on the measurement site. A detection unit housed in the second holding member detects a photoacoustic signal generated in the measurement site irradiated with the light beam emitted from the light emitting unit. A matching member is arranged between the second holding member and the measurement site, and is in contact with the measurement site.
