Abstract
A press-bonded sheet in which two sheet portions are press-bonded in a peelable state is manufactured by a method including steps of: forming an adhesive layer containing powder adhesive on a sheet; heating the adhesive layer to fix it to the sheet; opposing an area on the sheet where the adhesive layer is fixed and an area on the same sheet or on a different sheet where another adhesive layer is formed and fixed; and press-bonding the opposed areas. The fracture strain of a main constituent material of the powder adhesive is 10% or more and less than 1000%.
