Abstract
A jig body of resin is formed with a concave part engaging with an upper backside of teeth and another concave part engaging with a lower backside of teeth, and includes a portion coming into contact with an oral cavity part. An optical fiber bundle for measurement is embedded in the jig body, and a forward-end-surface of the optical fiber bundle is exposed on the portion of the jig body coming into contact with the oral cavity part and flush with the portion. A heater and a temperature sensor for keeping the temperature of the jig body constant as well as a pressure sensor for detecting a pressure for holding the jig body between the upper and lower teeth of a measured person are further embedded in the jig body.
