PROBLEM TO BE SOLVED: To improve adhesion of a sensor and a measuring object part of a specimen by narrowing a width of a flexible connecting part joined with a light receiving part and a light emitting part more than a width of the light receiving part and the light emitting part in an optical living body measuring sensor used by being stuck to a fingertip when measuring the content of a specific coloring matter in blood. SOLUTION: A light sensor 3 for inspecting a liver function is composed of a light emitting part 4 having a light emitting element 1, a light receiving part 5 having a light receiving element 2 and a connecting part 6 interposed between these, and the connecting part 6 is formed of mutually separately parallelley arranged two linear bodies. The sensor 3 constituted in this way has a surface where an LED and a PD contact with a measuring object part of a specimen and a plane for sticking a fixing tape 8 by opposing the surface. A hole surrounded by the light emitting part 4, the light receiving part 5 and the two linear bodies exposes an adhesive surface of the fixing tape 8 when sticking the sensor 3 to the measuring object part to become an adhesive part of the sensor 3 and the measuring object part to improve adhesion of the sensor 3.
