[Problem] To provide a syringe which has a user-friendly syringe needle, allays concerns pertaining to hygiene and danger before and after use, and allays anxiety from the invasiveness of the injection needle even during use. [Solution] A syringe comprising a syringe barrel 1, a needle-equipped gasket 2, and a plunger 4 to which a gasket 3 is mounted. In the injection cylinder 1, a container body 11 and a protective body 12 are integrally formed, and the protective body 12 is separated from a connection part 13 by being cleaved before use. An injection needle 22 is housed in the container body 11, and by operating the plunger 4 at the time of use, the injection needle 22 is exposed to the outside of the container body 11 and inoculates the skin. When doing so, two protruding parts 11C1, 11C2 at the tip of the container body 11 are brought into contact with the skin to press the epidermis and the dermis to such a degree that the epidermis and the dermis are not damaged, whereby another pain to the pain from the injection needle 22 is caused and the pain from the injection needle 22 is camouflaged and reduced. After use, the needle-equipped gasket 2 is returned to the inside of the container body 11 and the injection needle is housed therein.
