First Claim
1. A lancet for attachment to a housing of a lancing apparatus, comprising:
- a case provided separately from the housing of the lancing apparatus and including an internal space, and a lancing unit including a lancing needle and movable within the internal space in an advancing direction from a wait position to an advanced position;
wherein the case comprises a main body accommodating the lancing unit and having a tubular mounting portion for removable attachment to the housing of the lancing apparatus, and a cap directly connected to the main body, the cap being detachable from the main body;
wherein the lancing unit comprises a cover portion for covering a front end of the lancing needle, the cover portion being initially separate from the cap, the cover portion being brought into engagement with the cap;
wherein the cover portion is detached from the lancing needle together with detachment of the cap from the main body for exposing the front end of the lancing needle; and
wherein the main body keeps accommodating the lancing unit before attachment of the main body to the housing of the lancing apparatus and after removal of the main body from the housing of the lancing apparatus.

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).
