Abstract
Aspects of the invention can be an inexpensive biosensor capable of measuring a number of samples in a short time, and suitable for only one-time use (expendable). The biosensor according to the invention can include a light transmissive substrate, a probe fixing region provided on one face of the light transmissive substrate, a light emitting element provided on the other face of the substrate that irradiates the probe fixing region from the back side thereof, and a light receiving element provided on the other face of the substrate that detects the light intensity of the reflected light from the back side of the probe fixing region. Thereby, a biosensor formed in one substrate can be obtained.
