<P>PROBLEM TO BE SOLVED: To provide a cylinder of a syringe, having a lubricating thin layer derived from fluorine resin, which is integrally formed on the inner peripheral surface of the cylinder and very thin, and more reducing mixing of fluorine resin into a medical solution as compared with the prior art, and to provide a manufacturing method for a cylinder of a syringe or a lubricating thin layer, manufacturing the cylinder having the lubricating thin layer or the lubricating thin layer with good efficiency while restraining the growth of bacteria or being kept in the germ-free condition. <P>SOLUTION: In this cylinder of the syringe, the lubricating thin layer 2a derived from fluorine resin, which is generated by heating or pressurization or by both of them after the fluorine resin 2 is coated, is integrally formed on the inner peripheral surface of the cylinder 1, and the lubricating layer 2a is excellent in slidability and hardly separated even if a rubber slider 1a is moved, so that it is not mixed in a injection liquid. <P>COPYRIGHT: (C)2007,JPO&INPIT |
