Ceramic electronic component

摘要

A ceramic electronic component includes an electronic component body and first and second metal terminals. The electronic component body includes a bare ceramic body and first and second outer electrodes. The first and second outer electrodes of the electronic component body are connected respectively to the first and second metal terminals by solders containing Sn as a main constituent. An alloy layer containing Ni—Sn is provided in at least a portion of a bonding interface between adjacent two of the first and second metal terminals and the first and second outer electrodes.

1. A ceramic electronic component comprising:
an electronic component body including a bare ceramic body including two principal surfaces opposed to each other, two end surfaces opposed to each other, and two lateral surfaces opposed to each other, and outer electrodes arranged to cover the end surfaces of the bare ceramic body; and first and second metal terminals connected to the outer electrodes by solder containing Sn as a main constituent; wherein at least a Ni-plated film is provided on a surface layer portion of each of the outer electrodes; at least a Ni-plated film is provided on a surface layer portion of each of the first and second metal terminals; and an alloy layer containing Ni—Sn is provided in at least a portion of a bonding interface between an adjacent pair of the outer electrodes and the first and second metal terminals in a central region of each of the end surfaces.
