- the supply port 20 is positioned on the rear end 44 side of the knob plate 26 with respect to the folding line L of the knob plate 26, and the supply port 20 is protruded by bending the tip 27 side of the knob plate 26 with the folding line L. Since it moves backward by a distance D from the portion 107 to the rear end 44 side, the blood 30 attached to the finger 30 is brought into contact with the supply port 20 while the blood 100 adhering to the finger 30 is in contact with the supply port 20 corresponding to the curved shape of the finger 30. The position can be regulated.
- the biosensor 10 of the present invention may include a protruding tip 107 that forms the position restricting means 104 separately from the fold line L, as shown in FIG.
- the protruding tip portion 107 is separated from the through hole 40. Even in such a configuration, by bending the tip 27 side of the knob plate 26 along the folding line L, the supply port 20 protrudes to the outside and the protruding tip portion 107 protrudes to the outside to control the position.
- the means 104 is configured.
- the biosensor of the present invention by providing the knob plate, it can be easily held by a finger, and the length of the electrode can be shortened as much as possible to reduce the manufacturing cost. For this reason, it can be widely used as a biosensor for measuring blood sugar levels and the like.
- the biosensor of the present invention it is possible to easily and accurately contact the sample that is generated from the sample collection target and adheres to the sample collection target by providing the position regulating means. For this reason, it can be widely used as a biosensor for measuring blood sugar levels and the like.
