Abstract: The present invention relates to an electrically debondable adhesive sheet including, in this order, an electrically conductive substrate including a supporting substrate and an electrically conductive layer; a coating layer; and an electrically debondable adhesive layer in which an adhesive force is reduced by application of a voltage, in which the coating layer is formed on a surface of the electrically conductive layer on a side opposite to the supporting substrate, and the electrically debondable adhesive layer and the coating layer are in contact with each other.

Abstract: An optical-fiber-embedding sheet which is a strip-shaped sheet material containing an optical fiber to be used as a sensor and is configured of a base material and an adhesive layer formed thereover which is to be bonded to a placement object where the optical fiber is to be placed, the optical fiber having been embedded in the adhesive layer. The optical fiber is placed by applying a primer, which is for curing the adhesive layer by a chemical reaction with the adhesive layer, to a placement object for the optical fiber and thereafter applying the optical-fiber-embedding sheet to the portion of the placement object to which the primer has been applied.

Abstract: The present invention relates to a composition for peelable-coating-film formation including an elastomer and an amino-modified silicone oil, wherein a film formed from the composition for peelable-coating-film formation has a breaking strength of FB (N/20 mm) in a tensile test and a coating film formed from the composition for peelable-coating-film formation on a surface of an SUS304 plate has a peel adhesive force of FG (N/20 mm) in peeling from the SUS304 plate, FB/FG being 1.5 or larger.
