A method for manufacturing a chip ceramic electronic component that includes an outer electrode including a glass-free sintered layer including no glass. A glass-free conductive paste including a nickel powder, a metal powder, such as tin, having a melting point of lower than about 500 C., and a thermosetting resin, and not including glass, is applied to cover a portion of a surface of a ceramic body.

A signal line conductor extends in a direction in which a signal propagates, and a dielectric, surrounding the signal line conductor, also extends in the direction in which the signal propagates. Conductive films that define and function as a ground conductor extend on a side surface of the dielectric in the direction in which the signal propagates. Furthermore, conductive films that define and function as a bridge conductor extend on a side surface of the dielectric in a direction across the direction in which the signal propagates, and thus connect the conductive films to each other.
