PROBLEM TO BE SOLVED: To provide an agar-agar impression material infuser which is formed as a simple type, is applied to various kinds of impression sites by exchanging an infusion needle of the distal ends of a tube and eliminates the need for the conventional syringes and cartridges by directly setting the tube containing the agar-agar impression material to the infuser and infusing the agar-agar impression material. SOLUTION: This infuser comprises a disposable tube which is packed with the agar-agar impression material and the infuser which is set with this tube and extrudes the agar-agar impression material. The infuser has a long-sized casing which can be internally freely attachably and detachably set with the tube, a rotary moving roller for rolling the agar-agar impression material in the tube and a mechanism for extruding the agar-agar impression material from the infusion needle at the distal end of the tube extended with a nozzle when guided by this roller.
