Patent ID: 8475866

Claim:
A method for manufacturing a ceramic electronic component provided with a ceramic element assembly and external electrodes provided on the surface of the ceramic element assembly, comprising: performing an oil-repellent treatment by forming the external electrodes on the surface of the ceramic element assembly and subjecting the ceramic element assembly to an oil-repellent treatment through the use of an oil-repellent treatment agent to form a flux infiltration preventing film on the surface of the ceramic element assembly, wherein the oil-repellent treatment agent contains a polyfluoropolyether compound, as a primary component and hydrofluoroether as a solvent, wherein the polyfluoropolyether compound in the oil-repellent treatment agent is at least one type selected from the group consisting of the compounds described in the following items (I), and (II): C 3 F 7 O(CF(CF 3 )CF 2 O)yCF(CF 3 )-A, and (I) CF 3 O(C 2 F 4 O)yCF 2 -A, (II) where A represents —CONH(CH 2 ) 3 Si(OR) 3 , in which OR represents a methoxy group or an ethoxy group, and in the structural formulae in the items (I) and (II), y represents 4 to 40.
