A syringe needle assembly includes a needle tube and a hub. The needle tube has a needle body provided with a needlepoint configured to puncture a living body. To prevent the needle tube from dropping out of a holding member in which the needle tube is held, the needle body also includes an axially press-worked enlarged portion that is continuous in the circumferential direction of the needle body. The hub includes a fitting portion to which the enlarged portion of the needle tube is fitted, and holds the needle tube.
