PROBLEM TO BE SOLVED: To provide a practical producing method of a powder adhesive which enables coating (or transfer) by an electrophotographic system, and to provide its coating/press-bonding method. SOLUTION: This powder adhesive has a cyclic polyolefin as a basic constitution and is mixed powder having a particle diameter of about 9μm mixed with at least 30% of a hydrogenated resin component compatible with the cyclic polyolefin. At the production of a press-bonding printed material, the amount of the powder adhesive transferred to a press-bonding object pat is set to be 0.90-1.05 mg/cm<SP>2</SP>and the thermal press-bonding temperature of the press-bonding object part after fixing is nearly 120°C. Further, at the manufacturing of an envelope, a medicine bag, a widely used solid color bag or the like, the amount of the powder adhesive transferred to the press-bonding object part is set to be≥1.4 mg/cm<SP>2</SP>and the thermal press-bonding temperature of the press-bonding object part after the fixing is≥150°C.
