Abstract
A resonator 20 as an example of a laminated ceramic electronic component includes a first dielectric layer 22a. Two long and narrow holes (grooves) 24a and 24b are formed in the first dielectric layer 22a. A quadrangular cylindrical inner conductor 26 as a pattern electrode is formed in the vicinity of the holes 24a and 24b of the first dielectric layer 22a and inside the holes 24a and 24b. A second dielectric layer 22b and a first earth electrode 32a are formed on the first dielectric layer 22a. A third dielectric layer 22c, a second earth electrode 32b and a fourth dielectric layer 22d are formed under the first dielectric layer 22a.
