<p><P>PROBLEM TO BE SOLVED: To detect a faint optic element accurately in a biosensor provided with a light emitting element 24 and a light receiving element 26. <P>SOLUTION: The biosensor includes a board 22 that has optical transparency, the light emitting element 24 that is provided on a mounting face side of the board 22 and emits light, and the light receiving element 26 that is provided on a non-mounting face side of the board 22 and receives reflected light from a living body among the light emitted from light emitting element 24 to output a signal corresponding to the light reception. That is, the light receiving element 26 is provided for the board 22 on its non-mounting surface side opposite to the mounting surface side where the light emitting element 24 is provided, and is set back from a light emitting surface at a distance equal to or more than the thickness of the board 22. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
