摘要： A method of manufacturing a needle-equipped outer tube includes a preheating step comprising heating a distal end connecting section to a temperature at or below a softening point of a material forming an outer tube member with a joint member inserted in a distal end connecting section of the outer tube member, and with a needle being inserted or inserted and fixed in the needle insertion hole; and a joint member welding step, performed after the preheating step, comprising thermally welding the joint member to the distal end connecting section of the outer tube member with a distal end portion of the joint member pressed toward the proximal end of the joint member by a pushing member with a pressing force in a range of 4 N to 30 N.

摘要： A syringe and needle assembly including a needle tube having a needle tip for puncturing a living body. A syringe is formed integrally with the needle tube. The syringe includes a main body to be filled with a drug and a securing section that is formed integrally with the main body. The securing section has a close contact area that has an outer peripheral surface that contacts an inner surface of a cap when the cap is attached, and a connection area that connects the close contact area and the main body to each other. A needle tip of the needle tube protrudes from the close contact area, and a parting line is formed on the securing section. The outer peripheral surface of the close contact area has no parting lines.
