Abstract: A blood collection instrument includes a blood holding member with a structure in which a plurality of plate-shaped members are overlapped with each other and a collected blood holding passage formed between overlapped surfaces of the plate-shaped members; a connection part provided at an inflow port of the collected blood holding passage in the blood holding member; and a puncture member with a puncturing hollow needle connected to the connection part. An inner hole of the hollow needle of the puncture member is allowed to communicate with the collected blood holding passage in the blood holding member.

Abstract: A novel blood collection instrument with which it is possible to prevent blood from coming into contact with air during collection of blood, and a blood collection plate that is suitably used therefor. A blood collection instrument including: a blood holding member having a structure in which a plurality of plate-shaped members, are overlapped with each other and including a collected blood holding passage formed between overlapped surfaces of the plate-shaped members; a connection part provided at an inflow port of the collected blood holding passage in the blood holding member; and a puncture member including a puncturing hollow needle while being connected to the connection part. An inner hole of the hollow needle of the puncture member is allowed to communicate with the collected blood holding passage in the blood holding member.
