Abstract
A lancing device according to the present invention includes: a housing; a moving body movable relatively to the housing for forward movement of a needle; a driving mechanism for forward movement of the moving body; a hollow pressing portion at a front end of the housing for contact with a part where a puncture is to be made; and a pump mechanism capable of causing a vacuum to act inside the pressing portion. The pump mechanism is capable of adjusting the vacuum. The pump mechanism includes for example: a moving portion capable of reciprocating in a first direction and a second direction away from the first direction. Preferably, the adjustment of the vacuum is made by changing the number of reciprocations of the moving part in the first and the second directions.
