Abstract: The present invention improves the feeling in use when a finger is hooked on a finger grip. This syringe is provided with a cylinder 22, a syringe needle 24, a finger grip 30, and a plunger rod 32. The finger grip 30 is provided with a cylindrical portion and a pair of finger hook portions. The finger hook portion has an inclined curved surface 70 and an end-side curved surface 72. The inclined curved surface 70 is disposed on a side, of a side surface of the finger hook portion, connected to the cylinder 22. In the inclined curved surface 70, the inclination of a base-side region with respect to the center axis of the cylindrical portion is gentler than the inclination of an end-side region with respect to the center axis of the cylindrical portion. The end-side curved surface 72 is disposed at the boundary between the end of the finger hook portion and the inclined curved surface 70. The end-side curved surface 72 extends along the boundary.

Abstract: The present invention suppresses the amount of fluid pushed out from an injection needle when confirming whether air has been pushed out of the injection needle. Provided is a syringe that comprises: a cylinder 20; an injection needle 22; a needle base 24; an injection needle cover 26; and a plunger rod 28. The needle base 24 communicates between the inside of the cylinder 20 and the inside of the injection needle 22. The injection needle cover 26, when extended from a folded state, surrounds the injection needle 22. The injection needle cover 26 comprises an injection needle surrounding part. The injection needle surrounding part has at least one cutout 130 in a section facing the needle base 24 and covering the needle base, such that the needle base 24 can be identified from the outside.
