<P>PROBLEM TO BE SOLVED: To provide a connector made of a material suited to medical use, having superior productivity despite a slender body and enabling a firm connection, and to provide its formation method. <P>SOLUTION: In the formation method of the connector 1 provided at the end portion of a tube 4 for use in a medical field, a base substance 2 made of PP (polypropylene) and having a tubular projection 23 with a shape the same as that of the tube 4 is mounted within a mold K, then a pin P having an outer diameter the same as that of the tube 4 is applied to the tubular projection 23 to protect the projection end, polybutadiene being a material the same as that of the tube and being a liquid state by being heated to a temperature higher than the melting point of the PP is injected into the mold K till embedding the pin P to a predetermined length, and while the outer circumferential face of the tubular projection 23 is dissolved by heat to form a resin mixing area layer 26, an adapter part 3 is provided to include at least the portion of the tubular projection 23 and to form a lumen area for inserting the tube 4 at the tip of the tubular projection. <P>COPYRIGHT: (C)2009,JPO&INPIT |
