摘要： The present invention provides a method for manufacturing press-bonded sheets capable of peeling a product manufactured by a press-bonding process smoothly and with moderate force and of suppressing lowering of adhesive strength due to deformation of the product. The present invention relates to a method for manufacturing press-bonded sheets in which sheets are press-bonded in a peelable state, including: a step of forming an adhesive layer containing powder adhesive on the sheet; a fixing step of heating the adhesive layer formed on the sheet to fix it to the sheet; a step of superimposing by opposing an area on the sheet where the adhesive layer is formed and fixed and an area on0 the same sheet or on a different sheet where another adhesive layer is formed and fixed; and a press-bonding step of pressurizing the superimposed portion under heating and press-bonding it; wherein a fracture strain of a main constituent material of the powder adhesive is 10% or more and less than 1000%.
