Abstract: A protector is attached for use to a needle body having a main needle body and an enlarged-diameter section having an outer diameter greater than that of the main needle body. The protector includes a platelike protector body made of a metal material. The protector body includes a first section formed with a first hole adapted to receive the needle body when the needle body is passed therethrough, a second section formed with a second hole, and a third section adapted to connect the first section and the second section. The second hole of the second section is provided with a tubular portion that permits the main needle body to pass therethrough, but prohibits the enlarged-diameter section from passing through the tubular portion. In a state in which the protector covers the needle tip, the tubular portion comes into abutment against the enlarged-diameter section, thus prohibiting the needle body from moving toward the proximal side.
