A lancing device (X) comprising a first moving member (32) holding a lancing member (11) moved from a standby position to a puncturing position in a puncturing direction (N1), for puncturing a target portion by the lancing member (11). The lancing device (X) further comprises a second moving member (31) connected to the first moving member (32), for controlling the movement of the first moving member (32) upon the movement of the second moving member, and also comprises an impact absorbing means (23A) for absorbing impact that is caused when the first and the second moving members (31), (32) come to stop on puncture operation. The impact absorbing means (23A) includes an elastic member (23Ab) for absorbing impact by elastic deformation.
