A method for manufacturing a sheet-shaped body in which a powder particle layer is sandwiched between a base sheet to which a bonding agent is applied and a covering sheet so as to be bonded into an integral body, is provided with the steps of: shifting the base sheet, the powder particle layer and the covering sheet, with each of the sheets and the layer being held on the respective roller face, and after the powder particle layer has been transferred onto the base sheet, bonding the base sheet, the powder particle layer and the covering sheet into an integral form. Thus, the powder particle layer can be fixed to a predetermined position in a stable manner.
