PROBLEM TO BE SOLVED: To provide a method for manufacturing a ceramic electronic part, which has a step of heat treatment for effectively recovering the characteristics deteriorated by laser trimming. SOLUTION: A ceramic electronic part, such as a single plate capacitor 1, is provided, which comprises a part body consisting of an oxide ceramic obtained through steps of forming and baking a conductive film 3 comprising base metal. A laser beam is irradiated on the ceramic electronic part to partially remove the conductive film 3 for forming a trimmed part 5. In giving heat treatment thereafter to the resultant, heat treatment temperature is set to be 50% or more of the baking temperature [°C] in the baking step and to be less than the baking temperature, and heat treatment atmosphere is set to be log (redox average oxygen partial pressure [MPa] of metal base at the heat treatment) -8 or more and to be log (redox average oxygen partial pressure [MPa] of metal base at the heat treatment) +5 or below.
