An absorbent article is provided with a central elastic material for positioning in a state in which it is extended in the front/rear direction in the outer direction in relation to an absorbent body, and an elastic material cover sheet which abuts the outer direction side surface of the central elastic material. The elastic material cover sheet covers an extension region where the central elastic material is positioned in an extended state, and a non-extension region where the central elastic material is positioned in a non-extended state. An adhesive agent for fixing in the extended state is coated onto the central elastic material of the extension region. An adhesive agent is coated onto at least the non-extension region of the outer direction side surface of the elastic material cover sheet, and the adhesive agent coated onto the outer direction side surface penetrates to the inner direction side surface of the elastic material cover sheet.
