Abstract:
To provide excellent skin touch feeling, a compression resistant and durable concavo-convex shape providing an uneven feeling, and excellent absorption performance, a sanitary napkin is provided that includes an absorber interposed between a permeable front surface sheet embossed into a concavo-convex shape and a back surface sheet and a hydrophilic third sheet disposed between the permeable front surface sheet and the absorber. The permeable front surface sheet is a laminate structure that includes a fine fiber skin contact surface layer made of fine fibers having a fineness of less than 2.0 dtex and a crimped fiber layer laminated on the non-skin contact surface of the fine fiber layer and the crimped fibers have a fineness of from 3.0 to 5.0 dtex.
