Abstract
A multi-layer ceramic electronic part is made up of a laminated body in which a ceramic layer and internal electrodes laminated on one another, and external electrodes are provided at end portions of the laminated body. The internal electrodes reach to one of at least a pair of edges of the ceramic layer and oppose each other, thereby leading the internal electrodes to end surfaces of the laminated body and connecting the internal electrodes to the external electrodes. Pillar-like ceramic portions, continuous in a direction of thickness of a conductor film forming the external electrodes, are scattered in the conductor film. The ceramic portions of the external electrodes are formed so that they are continuous from an inner surface of the conductor film of the external electrodes, where they closely contact with a surface on the laminated body, up to an upper surface thereof. With this multi-layer ceramic electronic part, cracks due to heat-shock can be prevented from occurring within the laminated body, and also the property in soldering of the external electrode can be kept in good condition.
