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 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, the light receiving element and the light shielding portion disposed therebetween,wherein the cover comprises a roughened bottom surface that faces towards the light emitting element and the light receiving element and that is configured to scatter light passing through the cover.

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.
