Abstract
An electronic component includes a laminate and an external electrode provided on an end surface of the laminate. The external electrode includes a Ni layer provided on the end surface, a Ni—Sn alloy layer provided on the Ni layer, and a resin layer that is provided on the Ni—Sn alloy layer and includes metal grains including Sn grains. The Ni layer and the Ni—Sn alloy layer reduce or prevent intrusion of moisture from the external electrode into an interior of the laminate, and the resin layer reduces or prevents generation of cracks when a bending stress is applied to the external electrode.
