摘要： A condom disperses local tightening force at the opening end portion and maintains wind-up property. Further, it enables the drug to be automatically applied when it is being used to effectively prevent infection of diseases. The condom has a sperm reservoir at an end portion thereof and extends in a cylindrical form, wherein an open end portion includes elastic annular trapezoidal portions in cross section with notch and an elastic annular end with a hollow end portion. The condom may have sol type active drug in the porous hollow end portion, so that said drug is applied to the outer surface of the cylindrical portion when the condom is used.
