Publication number: 20220346625Abstract: Provided is, for example, a cleaner sheet including: a cleaning surface that is configured to be brought into sliding contact with a surface of an object to be cleaned. The cleaning surface has unevenness, and includes projections respectively having distal ends configured to be in sliding contact with the object to be cleaned when in use. The projections are constituted by a member formed to have the projections arranged at intervals from each other in a plane direction of the cleaning surface. The member has a hardness of 0.4 MPa or more measured by a nano-indentation method. The cleaning surface further includes adhesive recesses that have higher adhesive force than that of the member and are exposed on the cleaning surface.Type: ApplicationFiled: July 8, 2022Publication date: November 3, 2022Applicants: NITOMS, INC., NITTO DENKO CORPORATIONInventors: Hirofumi YAMADA, Hiroshi Nagami, Yosuke Suyama, Tsuneaki Omori, Yoshitake Shigematsu, Yoji Ebisu, Teiji Sakashita, Mao Suzukawa
