Abstract: A double-sided adhesive sheet has a laminate structure including a first adhesive layer containing an electrolyte, a second adhesive layer, and a conduction substrate. A double-sided adhesive sheet joined body includes, for example, an adhesive sheet having such a laminate structure, a first conductive adherend to which the first adhesive layer adheres, and a second adherend to which the second adhesive layer adheres. A method for joining/separating adherends includes joining first and second adherends to each other via the adhesive sheet, then applying a voltage to the first adhesive layer so as to generate a potential difference in a thickness direction of the first adhesive layer, and separating the first and second adherends from each other.

Abstract: A sticky cleaner is provided for use in removing organic dirt stuck on a surface of an article. The sticky cleaner comprises a dirt-collecting member that collects the organic dirt as it makes contact with the surface of the article. The dirt-collecting member comprises a PSA at a part where it makes contact with the surface of the article. The PSA comprises, as its base polymer, an acrylic block copolymer having a hard segment (A) and a soft segment (B) in one molecule.

Abstract: This invention provides a film having a novel function such that the film itself eliminates sebum dirt adsorbed on the film surface. The sebum absorption/diffusion film provided by the present invention is used for covering a surface of an article to prevent adsorption of sebum to the surface. It is characterized by absorbing sebum adsorbed on the film surface into the film and allowing it to diffuse inside the film.

Abstract: Provided is a sticky cleaner that can easily remove organic dirt adsorbed on a surface of an article with greater dirt-removing workability. The sticky cleaner provided by the present invention is used for removing organic dirt adsorbed on a flat surface of an article. The sticky cleaner comprises a dirt-collecting member that collects the organic dirt as it makes contact with the flat surface. In the dirt-collecting member, the part to make contact with the surface is formed with a PSA. The surface-contacting part of the dirt-collecting member exhibits an adhesive strength of less than 1 N/25 mm as a measured value based on the 180° peel test specified in JIS Z0237.

Abstract: Provided is a cleaner that can easily and efficiently remove organic dirt accumulated on a flat plate surface such as a display-input member (touch panel member) in a portable device. The cleaner (10) provided by the present invention is a pressure-sensitive adhesive plate surface cleaner (10) that comprises a pressure-sensitive adhesive body (30) having a removable pressure-sensitive adhesive and is used so as to allow the pressure-sensitive adhesive body (30) to contact a flat plate surface (2) of a plate such as a portable device (1) having a flat surface in order to remove organic dirt accumulated on the plate surface (2).
