1. A method for manufacturing a press-bonded sheet in which sheet portions are press-bonded in a peelable state, comprising:
a step of forming an adhesive layer containing powder adhesive on a 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 on 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 of the areas where the adhesive layer has been formed and fixed 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%.
