Example of the polyamide-imide powder includes a condensation product of trimellitic acid derivative and aromatic diamine. Example of the trimellitic acid derivative includes trimellitic anhydride; trimellitic anhydride monochloride; 1,4-dicarboxy-3-N,N-dimethyl carbamoyl benzene; 1,4-dicarbomethoxy-3-carboxy benzene; 1,4-dicarboxy-3-carbophenoxy benzene; and ammonium salts formed of trimellitic acid, ammonia, dimethylamine, triethylamine, etc. Among these, trimellitic anhydride, trimellitic anhydride monochloride, etc. are often used with preference. Example of the aromatic diamine includes 2,2-bis[4-(4-aminophenoxy)phenyl] propane; 2,2 bis[4-(4-aminophenoxy)phenyl] butane; 1,1-bis[4-(4-aminophenoxy)phenyl]cyclohexane; 1,1-bis[4-(4-aminophenoxy)phenyl]cyclopentane; bis[4-(4-aminophenoxy)phenyl]sulfone; bis[4-(4-aminophenoxy)phenyl]ether; 4,4′-carbonyl bis(P-phenylene oxy) dianiline, etc.
