Abstract: The present invention provides a lancet assembly which eliminates the need to remove a resin cover encapsulating a pricking element. Upon inserting a lancet structure into a lancet holder, a force which separates a lancet cover encapsulating the sharp tip portion of the pricking element from a lancet body is generated, and this force is allowed to act on the lancet cover and the lancet body to thereby expose, within the lancet holder, the sharp tip portion of the pricking element encapsulated by the lancet cover and to locate the opening of the lancet holder in front of the sharp tip portion of the pricking element.

Abstract: A lancet assembly is disclosed which eliminates the need for removing a resin cover that covers a pricking element. When a lancet structure is inserted into a lancet holder, a force is applied so as to separate a lancet cover, that encloses a distal end of a pricking element, from a lancet body so that the distal end of the pricking element which has been enclosed by the lancet cover is exposed in the lancet holder, and the opening of the lancet holder is positioned in front of the distal end of the pricking element. The lancet structure has a trigger which launches the pricking element of which the distal end is exposed, when the lancet structure is continually pushed into the lancet holder.
