Patent ID: 8164178

Claim:
A chip-type semiconductor ceramic electronic component comprising: a ceramic body made of a semiconductor ceramic; first external electrodes formed on opposite end surfaces of the ceramic body; and second external electrodes extending to cover surfaces of the first external electrodes and part of side surfaces of the ceramic body, wherein corner portions defined by the side surfaces and the end surfaces of the ceramic body have curved surfaces, and a curvature radius of the corner portion of the ceramic body is R (μm), wherein the first external electrodes are each made of a material having an ohmic property with respect to the ceramic body, and a maximum thickness of a portion of the first external electrode layer in contact with the ceramic body and measured from the end surface of the ceramic body is y (μm), wherein the second external electrodes are each made of a material not having an ohmic property with respect to the ceramic body, and a minimum thickness of a portion of the second external electrode in contact with the side surface of the ceramic body and measured from an apex of the corner portion of the ceramic body is x (μm), and 20≦R≦50, − 0 . 4 x+0.6≦y≦0.4 when 0.5≦x≦1.1, and −0.0076 x+0.16836≦y≦0.4 when 1.1≦x≦9.0.
