Forward movement of a pushing unit is stopped just before the pushing unit abuts against a rear end of a syringe to reliably prevent unwanted extrusion of a chemical liquid from the syringe. An injecting apparatus for injecting a chemical liquid includes: an injection head to which a syringe filled with the chemical liquid is to be mounted； a pushing unit provided on the injection head and pushing a rear end of the syringe； a rear end detection unit provided on the injection head and detecting the rear end in a contactless manner； and a control unit configured to control the injection head, the control unit acquiring a forward movement distance that the pushing unit is to be moved forward after the rear end is detected, and causing the pushing unit to move forward by the forward movement distance after the rear end is detected and to stop at a position separated from the rear end.
