Abstract
A manufacturing apparatus is provided to manufacture a sheet-like member by joining a non-woven fabric to another member of an absorbent article. This apparatus includes a bulk restoring device that restores bulk of the non-woven fabric through heating the non-woven fabric by blowing hot wind onto the non-woven fabric while conveying the non-woven fabric along a conveying direction, the non-woven fabric being continuous in the conveying direction, and a joining device that joins the non-woven fabric whose bulk has been restored with the hot wind to the other member using an adhesive, the non-woven fabric being at a higher temperature than a temperature before being heated with the hot wind.
