1. A biosensor, comprising:
- a light transmissive substrate;
a plurality of probe fixing regions provided on a first face of the light transmissive substrate;
a light shielding region formed in the light transmissive substrate that shields light between the probe fixing regions; and
each of the probe fixing regions including, on a second face of the light transmissive substrate, a light emitting element that irradiates a corresponding probe fixing region from a transmissive substrate side, and a light receiving element that detects light intensity of reflected light from the light transmissive substrate side of the corresponding probe fixing region.

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.
