The purpose of the present invention is to provide an intraocular lens injector with which the tip side of a plunger can be finely formed while ensuring rigidity, and with which the occurrence of shaft deviation during contact with an intraocular lens can be effectively inhibited. A plunger (3) of this intraocular lens injector (1) is provided with: a tip-side shaft part (35) provided with an L-shaped section (36) a central shaft part (33) which is formed flat, and which is wider than the tip-side shaft part (35) and a part (40) to be restricted which is formed from the tip-side shaft part (35) to the central shaft part (33), and which protrudes from the flat surface at the central shaft part (33). Furthermore, an opening (70) in a main body (2) is provided with: a central opening (71) which is open in accordance with the shape of the central shaft part (33) and a restriction part (72) formed so as to protrude from the end surface of the central opening (71), in the thickness direction of the central shaft part (33), in accordance with the shape of the part (40) to be restricted. The part (40) to be restricted has a length in the axial direction which is set such that the part (40) to be restricted is restricted by the restriction part (72) in an interval from an initial position before the L-shaped section (36) begins to be in contact with a second lens support part (93) of an intraocular lens (90), to a position in which the L-shaped section (36) is in contact with the second lens support part (93).
