1. An injection device with puncture function comprising, in a single casing:
- a cartridge in which a chemical solution is enclosed, said cartridge having a needle inserted at a front end thereof;
a cartridge holder into which the cartridge is inserted;
a reciprocation means for reciprocating the cartridge and the cartridge holder; and
an extrusion means for extruding the chemical solution from a rear end of the cartridge toward the needle;
wherein said reciprocation means reciprocates the cartridge and, at this time, a motion speed and an amount of motion of the reciprocation means are variable, and puncture by the needle or administration of the chemical solution through the needle is carried out.
