SOLUTION: The ring 3 is formed at the opening end 13 of the condom main body 10 and also the independent ring 5 is formed just above it at prescribed interval. Besides, the clogging end 13 of the main body 10 is molded in a nipple shape and formed as a body fluid storing part. In this case, the inner and outer diameters of the ring 5 are set to be smaller than those of the main body 10 so as to improve the coming-off preventing function of the main body 10. Besides, plural prescribed parts 11 and 12 in the lower half part of the main body 10 are molded in a taper shape where the inner diameter of the main body 10 gradually becomes smaller till it coincides with the inner diameter of the ring 5 continued from it and, in the meantime, the same diameter is set from a lower side part 12 to the opening end 13 of the main body 10.
