BIOSENSOR
First Claim
1. A biosensor comprising:
- a wiring board;
a light emitting element and a light receiving element disposed on a principal surface of the wiring board;
a light-emitting-element sealer disposed on the principal surface of the wiring board and adjacent to the light emitting element to seal the light emitting element;
a light-receiving-element sealer disposed on the principal surface of the wiring board and adjacent to the light receiving element to seal the light receiving element;
a light shielding portion disposed between the light-emitting-element sealer and the light-receiving-element sealer;
a base medium with light transmitting properties, disposed in parallel with the wiring board with the light shielding portion therebetween; and
an adhesion layer with light transmitting properties disposed between the base medium and at least one of the light shielding portion, light-emitting-element sealer and the light-receiving-element sealer, and the adhesion layer provided to bond the base medium with the at least one of the light shielding portion, the light-emitting-element sealer portion and the light-receiving-element sealer,wherein the adhesion layer and the base medium do not overlap at least one of the light-receiving-element sealer and the light-emitting-element sealer when viewed from a direction normal to the principal surface of the wiring board.

Abstract
A biosensor including light emitting elements and a light receiving element disposed on a principal surface of a wiring board; a light shielding portion disposed between a light-emitting-element sealing portion and a light-receiving-element sealing portion; a base medium having light transmitting properties, disposed in parallel with the wiring board with the light shielding portion therebetween; an adhesion layer having light transmitting properties that bonds the base medium with the light-emitting-element sealing portion, the light-receiving-element sealing portion, and the light shielding portion; and a first electrocardiograph electrode attached to a principal surface of the base medium. Both end portions of the adhesion layer and both end portions of the base medium are disposed such that they overlap neither of the light-receiving-element sealing portion nor the light-emitting-element sealing portion when viewed from a direction normal to the principal surface of the wiring board.
