Japanese Patent Publication No. 2004-528090

As a result of studies by the inventors of the present application, in the absorbent article described in Patent Document 1, the cooling sensation agent imparts a cooling sensation to the wearer's skin, thereby improving the wearing sensation. It has been found that the agent tends to plasticize the fastening portion for fastening the absorbent article to the garment.

In particular, the inventors of the present application have found that increasing the amount of the cooling sensation agent in order to improve the wearing feeling even when the absorbent article is used for a long period of time causes the fixing portion of the absorbent article to become loose during use. It has been found that the fixing part is plasticized by the cooling agent, and the plasticized fixing part is separated from the clothes, which may cause the user to feel uncomfortable. In addition, since the fixing portion is separated from the clothing, the absorbent article is separated from the wearer's skin, and the cooling sensation agent is less likely to impart a cooling sensation to the wearer's skin, which may impair the wearing feeling. I found out.
Accordingly, an object of the present disclosure is to provide an absorbent article that is easy to keep feeling cool even when used for a long period of time and that continues to be excellent in wearing feeling.
