摘要：
The present invention relates to a lancing device (1A) that includes a moving member (4) for moving a needle (20b) in an advancing direction (N1) from a standby position to a puncturing position, and also includes a contact portion (36) for contacting with a puncturing target (S). The lancing device (1A) applies a suctioning force to the moving member (4) to move the moving member (4) in a retreating direction so that the moving member (4) is brought to the standby position. The lancing device (1A) is provided with a decompression space (35) which is decompressed for applying the suctioning force to the moving member (4). Preferably, the pressure in the decompression space (35) is reduced to be smaller than the atmospheric pressure by a predetermined value, thereby moving the moving member (4) in the retreating direction.
