PURPOSE: An injection needle for cell injection and a syringe including thereof are provided to prevent leaking of cell solution which is injected into cardiac muscles by forming an injection needle shaft in a spiral shape.CONSTITUTION: An injection needle for cell injection(10) includes a spiral shaped needle shaft(11). A plurality of openings is formed on side of the injection needle shaft. The needle shaft includes bioabsorbable material in order to decompose within organs. The needle shaft comprises a second shaft of bioabsorbable material which is made of metal and a first shaft.
