Abstract: Disclosed is a men's brief adapted to support wearer's scrota and a phallus separately from each other and to prevent the phallus from coming into contact with a skin on the scrota or a groin area. The men's brief comprises a shrunken section (3) for tightening a boundary between scrota (B) and a phallus (A), which is formed by folding strip shaped portions along a middle longitudinal line and the both side longitudinal lines of its front part surrounding the scrota (B) and the phallus (A) and sewing each of the strip shaped portions longitudinally, a first bulged section (3-1) disposed above the shrunken section (3) and adapted to surround and support the phallus (A), and a second bulged section (3-2) disposed under the shrunken section (3) and adapted to surround and support the scrota (B), wherein the first and the second bulged section (3-1, 3-2) are provided by formation of the shrunken section (3).
