Provided is a needle cover with good manipulability wherein, when a winged needle is drawn into the covert main body, the cover main body is easily expanded, rattling of the wings is minimized, allowing stably fixing the wings. The cover main body (2) has a needle introduction part (3) and a needle introduction part (5). An opening (30P) is formed on the bottom (D) side of the needle introduction part (3), and the needle protection part (5) has a first needle protection part (the top protection part)(5.1) on the top (U) side and a second needle protection part (the bottom protection part) (5.2) on the bottom (D) side. An opening (5OP) is formed between the bottom (D) side of the first needle protection part (5.1) and the top side of the second needle protection part (5.2), and the first needle protection part (5.1) and the second needle protection part (5.2) are connected on the base (PE) side by a needle protection part connection unit (5H) and have a terminal opening (5OPDE) on the terminal (DE) side. On the base (PE) side, a wing-fixing unit (7) is formed on the first side (S1) and the second (S2) of the second needle protection part (5.2), and an locking part (7T) of the wing-fixing unit (7) is formed on the terminal (DE) side.
