- the coating pattern when bonded by hot melt bonding is, for example, Spiral coating, control seam coating, coater coating, curtain coater coating
- the basis weight of the adhesive in hot melt bonding is preferably lg / m 2 to 30 g / m 2, more preferably 3 g / m 2 to 10 g / m 2 . Also, in the case of a pattern in which the adhesive is applied in a linear shape, the wire diameter is preferably 30 m to 300 ⁇ m! /.
- the base sheet 61, 62 either a liquid permeable sheet or a liquid impermeable sheet can be used.
- a liquid permeable sheet for example, the liquid permeable sheet exemplified as the top sheet 11 can be used.
- the base sheet 61, 62 is a spunbond nonwoven fabric, a point bond nonwoven fabric, a span lace nonwoven fabric, etc., as long as it is a thin nonwoven fabric, and a nonwoven fabric having a fiber basis weight of lOgZm 2 to 30 gZm 2 can be obtained. It can be illustrated. This is because the thin nonwoven fabric is more smooth in the stretched state of the belt-like portion.
- the liquid-impermeable sheet exemplified as the back sheet 14 can be used.
- the liquid-impermeable sheet may be on the skin contact surface side or on the non-skin contact surface side with respect to the elastic member.
- the elastic member 63 for example, natural rubber or synthetic rubber such as styrene-butadiene, butadiene, or isoprene can be used.
- the sheet-like elastic member if example embodiment, use a non-woven fabric or the like fiber basis weight foamed polyurethane 80GZm 2 from 30GZm 2, fiber basis weight is also mixed fibers force of polyurethane and polypropylene 20GZm 2 force also 70GZm 2 is formed! / I can.
- spiral coating and control seam Apply hot melt adhesive by coating method such as coating, coater coating, curtain coater coating, summit gun coating, etc.
- the base material sheets 61 and 62 are overlapped and joined to each other.
- the elastic member 63 may be coated in advance by a coating method such as slit coating or control seam coating.
- bonding is not limited to the above hot melt bonding, and for example, heat sealing, ultrasonic sealing or the like may be used alone or in combination.
