The present invention provides disposable panty-type underwear which is easy to wear, has high fit to the wearer's body, and can be manufactured with a small amount of material, and a manufacturing method thereof. The manufacturing method of disposable panty-type underwear (10) is characterized by comprising: forming a laminated body in which each elastic body (103) is bonded between a net-shaped inner surface sheet (101) and an outer surface sheet (102) The process of (100A), along the
crotch side end edge (11a, 12a) shared by the abdominal part (11) and the back side part (12) in the conveying direction of the net, the predetermined line of
cutting (C) that is periodically continuous is paired. The process of
cutting the laminated body (100A), the process of bridging the
crotch part (13) at the two central parts of the abdominal part (11) and the back side part (12) of each cycle, the
crotch part (13) is The jointed continuum (100B) is bent, and the two ends (16, 16) perpendicular to the conveying direction of the net are joined and
cut according to each period; the planned
cutting line (C) of each period includes: Two end lines (11b, 11b, 12b, 12b) parallel to the feeding direction of the net, a pair of inclined lines (11c, 11, 12c, 12c) inclined from the two end lines to the center and to the ventral part (11) side, the two The
central line (11d, 12d) connecting the oblique lines.
