A method of forming an electrode in a ceramic transducer electronic component is provided. The method includes preparing a sintered body for a ceramic transducer containing a metal oxide, performing patterning by irradiating a laser on a surface of the sintered body for a ceramic transducer, and forming a metal electrode by performing an electroless plating process on the sintered body for a ceramic transducer on which the patterning is formed, wherein, in the performing of the patterning by irradiating the laser on the surface of the sintered body for a ceramic transducer, the patterning is performed by irradiating the laser that satisfies at least one of a predetermined power condition and a predetermined processing speed condition.
