Abstract
The needle tip protector is attached to a puncture needle and prevents exposure of a needle tip by being moved to the needle tip side, and includes a first side plate and a second side plate extending from a bottom part located on a needle base side of the puncture needle to the needle tip side, and facing each other while sandwiching the puncture needle from both sides. The first side plate and the second side plate include lateral cover pieces protruding inward in a direction of facing at respective widthwise edges, which are opposite to each other in a plate width direction. With the needle tip protector attached to the puncture needle, the puncture needle is located between the respective lateral cover pieces of the first side plate and the second side plate.
