A lancet device includes a shot prevention mechanism for preventing re-shooting using a used lancet, that inhibits movement to a shot-ready completion state where a puncture body is held at different positions within a casing before and after use. A holding position of the puncture body within the casing before use is different than a holding position after use. When the used lancet is fitted to a main body, a stopper plate does not operate, and a setting release button remains in a depressed state and does not pushed up.
