This injection needle assembly is provided with a needle tube, a needle hub, a main body part, a coupling part, and an impelling part. The main body part is capable of moving between a first position which is away from the tip of the needle tube, and in which the tip of the needle tube is exposed, and a second position in which the tip of the needle tube is covered. Furthermore, in the first position, at least a portion of the main body part protrudes further towards the side of the tip of the needle tube than a contact surface. |
