Abstract

A circuit board for body fluid collection includes a measurement unit including a puncture needle and an electrode for making contact with the body fluid collected by the puncturing with the puncture needle, wherein the measurement unit is provided in a plural number and disposed radially on a same plane.

Claims

1. A circuit board for body fluid collection comprising a measurement unit including a puncture needle and an electrode for making contact with the body fluid collected by the puncturing with the puncture needle,

wherein the measurement unit is provided in a plural number and disposed radially on a same plane.

2. The circuit board for body fluid collection according to claim 1, wherein the measurement unit comprises a bending portion that is bendable at an upstream side of a distal end of the puncture needle in the puncturing direction.

3. The circuit board for body fluid collection according to claim 1, wherein an opening is provided at a center of the circuit board for body fluid collection, and

an engage portion that can be engaged with a driving member for rotating the circuit board for body fluid collection in a circumferential direction is formed at an inner circumferential surface of the opening of the circuit board for body fluid collection.

4. A biosensor comprising a circuit board for body fluid collection, said circuit board for body fluid collection comprising:

a measurement unit including a puncture needle and an electrode for making contact with the body fluid collected by the puncturing with the puncture needle,

wherein the measurement unit is provided in a plural number and disposed radially on a same plane, and

a determination unit that is electrically connected to the electrode and performs a measurement on a component in body fluid.
