Abstract: When a monolithic ceramic electronic component is viewed from either one of end surfaces thereof, an outer electrode includes a solder-repellent portion and a solder-receivable portion. The solder-repellent portion covers the central portion of an end surface of a ceramic laminate body. The solder-receivable portion includes portions disposed on two opposing sides of the solder-repellent portion. When the monolithic ceramic electronic component is mounted on the circuit board, solder does not adhere to a portion around the central portion of the end surface. Thus, expansion and contraction that occur as a result of application of an AC voltage are not significantly transmitted to the circuit board. Consequently, vibrations of the circuit board are reduced.

Abstract: Solder-repellent portions are each arranged so as to extend over all or substantially all of a portion of a corresponding one of outer electrodes provided on a corresponding one of end surfaces of a monolithic ceramic electronic component and partially on portions of the outer electrode provided over two side surfaces of the monolithic ceramic electronic component. When the monolithic ceramic electronic component is mounted on the circuit board, solder does not adhere to the end surfaces and portions of the outer electrode provided on portions of the two side surfaces. Thus, expansion and contraction that occur as a result of application of an AC voltage is not transmitted or is not significantly transmitted to the circuit board. Consequently, vibrations of the circuit board are significantly reduced or prevented.
