PROBLEM TO BE SOLVED: To provide a puncture device improving a puncture track of a puncture needle and avoiding "double pricking" of the puncture needle.SOLUTION: A lancet device comprises a puncture member and a pressing member. In the lancet device, the puncture member comprises a needle shaft component including a puncture needle, a driving shaft component, and an intermediate shaft component therebetween, the needle shaft component, the driving shaft component and the intermediate shaft component being connected to each other via a joint component. When a pricking operation is performed, the driving shaft component of the puncture member is at least partly rotated by being pressed by a pressing action of the pressing member, and thereby the intermediate shaft component of the puncture member is displaced causing the needle shaft component to move in a puncture direction.SELECTED DRAWING: Figure 1 |
