To prevent feces from sticking to the scrotum when a diaper is worn and facilitate the clearance work by forming a scrotum extraction port extracting the scrotum of the male genital organ to the outside at the middle section along the longitudinal direction of the paper diaper stored with a rectangular water absorbing mat in a plastic bag.

A water absorbing mat overlapped with multiple sheets of Japanese paper is stored in a rectangular bag formed with a water-permeable plastic nonwoven fabric such as polypropylene on the surface and with a water- nonpermeable plastic sheet such as a polyethylene film on the back face to form a rectangular paper diaper for male 1. A scrotum extraction port 6 extended in the width direction is opened at the middle section in the longitudinal direction of the paper diaper for male 1. When the paper diaper 1 is used, it is fitted to a bedridden male, then the scrotum 11 of the male genital organ is extracted from the scrotum extraction port 6 to the outside of the paper diaper 1, and a diaper cover 7 is put on the paper diaper 1 and fixed.
