The present invention provides a lancing apparatus (X1) for moving a lancing element (11) in a lancing direction (N1) from a wait position to a lancing position to lance an intended portion with the lancing element (11) . The lancing apparatus (X1) includes a first member (31) which is reciprocally movable in the lancing direction (N1) and in a retreating direction (N2) which is opposite from the lancing direction (N1), and a second member (32) which moves along with the lancing element (11) and performs reciprocal movement in the lancing direction (N1) and the retreating direction (N2) in accordance with the movement of the first member (31).
