Provided are a syringe barrel having an injection needle, in which the injection needle is reliably fixed to the syringe barrel and in which the injection needle and a syringe nozzle are in reliable intimate contact with each other, a syringe having an injection needle, a die for molding the syringe barrel having an injection needle, and a method of molding the syringe barrel having an injection needle. A syringe barrel (1) having an injection needle, the injection needle (12) being made of metal and being integrally attached by injection molding to a synthetic resin syringe nozzle (113), wherein the area of contact of the injection needle (12) with the syringe nozzle (113) is in the range of 11 to 50 mm<SUP>2</SUP>. In another example of the invention, there is provided a syringe barrel (1) having an injection needle, the injection needle (12) being made of metal and being integrally attached by injection molding to a synthetic resin syringe nozzle (113), wherein an end section (122) located on the side opposite a needle tip (121) projects to the inner cavity of the syringe barrel (1) by an amount of 0.4 to 11 mm. |
