The lancet assembly 100 contains a lancet 101 and a protective cover 102, characterized in that (1) the lancet comprises a lancet body 104, lancet cap 106 and a pricking member 105, the pricking member is disposed in the lancet body and the lancet cap while straddling them members, and the distal end portion 124 of the pricking member is enclosed by the lancet cap; and (2) the protective cover is disposed around the lancet body, so that it is able to move to a position, after pricking, around the distal end portion of the pricking member that protrudes forward from the lancet body.
