Abstract: In a multilayer ceramic capacitor, SG represents an average of a distance between end portions of inner electrodes in a width direction and side surfaces of a ceramic body, OT represents an average of a distance between inner electrodes closest to main surfaces and the main surfaces, ET1 represents an average of dimensions of each portion of third and fourth terminal electrodes located on the main surfaces, and ET2 represents an average of dimensions of each portion of the third and fourth terminal electrodes located on the side surfaces. A dimension of the ceramic body in the width direction is larger than a dimension of the ceramic body in the height direction and Equations (1) and (2) are satisfied: SG>OT  (1) ET1>ET2  (2).

Abstract: A method of producing a ceramic electronic component includes baking a first electrode paste containing a metal powder at a first temperature to form a first electrode layer at a first region of a ceramic body, baking a second electrode paste containing a metal powder of the same type as the metal powder in the first electrode paste at a second temperature lower than the first temperature to form a second electrode layer at a second region different from the first region of the ceramic body, and applying a physical shock treatment to a surface of the second electrode layer to densify a surface layer portion of the second electrode layer.

Abstract: A multilayer ceramic electronic component includes a laminated body, a first external electrode, a pair of second external electrodes, and a pair of insulating coating portions. The insulating coating portions extend in a laminating direction between each of the second external electrodes and the first external electrode on a second principal surface, and from the second principal surface to respective portions of first and second side surfaces. A maximum thickness of the first external electrode on the second principal surface is larger than a maximum thickness for each of the second external electrodes on the second principal surface. A maximum thickness for each of the insulating coating portions on the second principal surface is larger than the maximum thickness of the first external electrode on the second principal surface.
