BIOSENSOR
First Claim
12. 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 emitting element to seal the light receiving element;
a light shielding portion disposed between the light-emitting-element sealer and the light-receiving-element sealer; and
a cover with light transmitting properties disposed in parallel with the wiring board with the light emitting element, light receiving element and the light shielding portion therebetween.

Abstract
A biosensor includes 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, configured to bond 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. The refractive index of the base medium is set to be higher than that of the adhesion layer, and a surface of the first electrocardiograph electrode which is adjacent to the base medium is roughened so that stray light passing through the base medium will be scattered.
