A medical agent injection device (10A) is provided with a tube-like body (12) which is filled with a medical agent, a pusher (14) which can be inserted into the hollow section of the tube-like body (12), and a filling member (16) which can be displaced in the axial direction relative to the pusher (14). The filling member (16) has a head section (42) which is inserted into the hollow section of the tube-like body (12) in a liquid-tight manner at a position closer to the front end than the pusher (14). The medical agent is filled into the tube-like body (12) by moving the filling member (16) backward relative to the tube-like body (12), and the medical agent having been filled into the tube-like body (12) is discharged from a medical agent discharge opening (12a) by rotating and moving the pusher (14) forward to move the head section (42) toward the front end. |
