PROBLEM TO BE SOLVED: To enable to reduce resistance by friction on drawing out an inner needle, by making a specific ratio of silicone oil be contained in rubber film in a seal cap for an indwelling needle with an inner needle penetrating part which is loaded with a rubber film so as to block the inner needle penetrating part. SOLUTION: A cap main body of this seal cap is a cylinder shape with the bottom and has an inner needle penetrating part on the bottom part, and a rubber film with the outer diameter almost equal to the inner diameter of the cap main body 11 is loaded so as to block the inner needle penetrating part 13. Though the shape of the cap main body is not especially limited if it is mountable on a lure connector, the preferable shape is one to be mounted on the lure connector by screwing. Silicone rubber, not so deteriorated by aging, containing 1-20wt.%, especially 3-8wt.%, of silicone oil is preferable. |
