BLOOD SENSOR AND BLOOD EXAMINING INSTRUMENT INCLUDING SAME
First Claim
1. A blood sensor comprising:
- a substrate;
a spacer that is attached on an upper surface of the substrate;
a cover that is attached on an upper surface of the spacer;
a blood storing part that is formed of a substrate hole which is formed in the substrate, a part of a spacer hole which is formed in the spacer and which is coupled to the substrate hole, and a cover hole which is formed in the cover and which is coupled to the spacer hole;
a supply channel that is formed of another part of the spacer hole and that communicates with the blood storing part; and
a plurality of detection electrodes formed on the supply channel,wherein the cover projects from a supply channel side toward an interior of the blood storing part, beyond the substrate and the spacer.

Abstract
A blood sensor (20a) comprises a substrate (21); a spacer (22) attached to the top of the substrate (21); a cover (23) attached to the top of the spacer (22); a blood reservoir portion (24) defined by a substrate hole (21a) formed in the substrate (21), a part of a spacer hole (22a) formed in the spacer (22) and connected to the substrate hole (21a), and a cover hole (23a) formed in the cover (23) and connected to the spacer hole (22a); a supply passage (25) defined by another part of the spacer hole (22a) and communicating with the blood reservoir portion (24); and detection electrodes formed in the supply passage (25). The cover (23) projects from the supply passage (25) toward the inside of the blood reservoir portion (24) farther than the substrate (21) and the spacer (22).
