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.
