Publication number: 20200129682Abstract: A supporter for body (1) to be attached to a skin of a body includes a pad base member (10) which is made of an elastic member and has a curved shape at least locally, and an adhesion layer (11) which is provided in a surface of the pad base member (10) on a side being adhered to the skin. The adhesion layer (11) is adhered to the skin with the curved shape of the pad base member (10) being stretched along a shape of the body, and holds the skin in a state in which the skin is drawn up, using a restoring force of the pad base member (10).Type: ApplicationFiled: October 31, 2018Publication date: April 30, 2020Inventors: Aya TAKEUCHI, Fumito TAKEUCHI, Tomoaki ITO, Kazuoki NAKAI, Kenzo KASE
