ねた結果次の考案に到達した。2. Description of the Related Art As shown in FIG. 2, a conventional plug 11 requires a sufficient thickness T of a welded portion L on a main body 15 because an infusion needle does not penetrate during use. The film 12 was welded to this, as determined by an experiment (in FIG. 2, 13 is a rubber stopper, and 14 is a rubber stopper). However, this plug 11 has the following disadvantages. (A) When the body 15 and the film 12 are sandwiched by a mold and subjected to thermal welding, a sufficient amount of heat is not transmitted because the thickness T of the welded portion L is large, so that there are portions where thermal welding is insufficient. In some cases, the welded portion was peeled off and leaked. (B) Further, as described above, since the amount of heat is not easily transmitted, the welding time is lengthened, and the manufacturing cost is increased. The inventor of the present invention has conducted extensive studies to solve the above problems, and has reached the following invention.

And the inner diameter d2 of the welded portion L1,
The thickness of the tube wall can be reduced. For this reason, when the main body 5 is inserted into the opened film 2 and sandwiched by a semicircular mold and thermally welded, the temperature of the welded portion rises quickly, and the speed is increased reliably and speedily.

１に示したようにテ−パ−状に設けるのが好ましい。As a result of experimentally determining the values of the welded portion L1 and the non-welded portion L2, for example, the thickness T1 of the tube wall of the welded portion L1 is 0.6.
It is found that the thickness is suitably from 1.5 mm to 1.8 mm, and the thickness T2 of the tube wall of the non-welded portion L2 is preferably 1.5 mm or more. When the outer diameter d3 of the welding portion L1 of the main body 5 is 18 mm, the inner diameter d2 of the welding portion L1 is 14.8 mm to 14.8 mm.
It is preferable that the inner diameter d1 of the non-welded portion L2 be 6.8 mm or less. In the present invention, the inner diameter d of the non-welded portion L2
1. The design can be changed in any manner as long as the relationship between the thickness T2, the inner diameter d2 of the welded portion L1, and the thickness T1 is d1 <d2 and T1 <T2. The step between the welded portion L1 and the non-welded portion L2 may be a right angle, but is preferably provided in a tapered shape as shown in FIG.
