Abstract
The present invention provides a lancet (X1) which includes a case (1) including an internal space (10), and a lancing unit (2) which includes a lancing needle (20) and which is movable within the internal space (10) in an advancing direction from a wait position to an advanced position. The case (1) includes a main body (11) accommodating the lancing unit (2), and a cap (12) which is molded integral with the main body (11) and detachable from the main body (11). The lancing unit (2) includes a cover portion (22) for covering a portion of the lancing needle (20) on the advancing side, for example. The cover portion (22) is detachable together with the cap (12) by exerting a rotational force for rotating the cap (12) and a pulling force for causing relative movement of the cap (12) in the advancing direction for exposing a front end of the lancing needle (20).

23. A lancing apparatus for advancing a lancing needle incorporated in a lancet mounted on the lancing apparatus, the lancet comprising:
- a lancing unit including a lancing needle;
a case holding the lancing unit movably from a wait position to an advanced position; and
retreated position holding means for holding the lancing unit at a retreated position after the lancing unit is retreated from the advanced position,wherein the lancing apparatus comprises a movable member which is movable in an advancing direction and is arranged to hold a retreat-side portion of the lancing unit; wherein the movable member moves in the advancing direction for bringing the lancing unit to the advanced position; wherein the case is moved in the advancing direction relative to the lancing apparatus to detach the lancet from the lancing apparatus, the detachment being performed while the lancing unit is held at the retreated position by the retreated position holding means after the lancing unit is moved in a retreating direction relative to the case.
