To provide a manufacturing method of an absorptive article capable of adhering nonwoven fabric arranged on the back surface of an absorptive main body and a peeling sheet with optimum adhesive power such that a tackiness agent is not left on the peeling sheet or underwear and the nonwoven fabric is not destroyed.

The manufacturing method of the absorptive article is a method of sticking the peeling sheet 7 to a nonwoven fabric sheet 3 of the absorptive main body 2 provided with the nonwoven fabric sheet 3 as the lowest layer on the lower surface of a liquid impermeable back sheet 6, and includes the following first - third processes. In the first process, a tackiness agent 12 for slip prevention is atomized or coated on the surface of the peeling sheet 7 and a tacky layer 12A is formed. In the second process, the nonwoven fabric sheet 3 and the back sheet 6 are joined with an adhesive material 11 for oozing. In the third process, the absorptive main body 2 and the peeling sheet are joined, the adhesive material 11 for oozing is oozed to the surface of the nonwoven fabric sheet 3 by pressurization, and the adhesive layer 11A and the tackiness layer 12A are joined with each other and fused.
