Abstract
A monolithic semiconducting ceramic electronic component includes barium titanate-based semiconducting ceramic layers and internal electrode layers alternately deposited, and external electrodes electrically connected to the internal electrode layers. The semiconducting ceramic layers contain ceramic particles having an average particle size of about 1 μm or less and the average number of ceramic particles per layer in the direction perpendicular to the semiconductor layers is about 10 or more. The internal electrode layers are preferably composed of a nickel-based metal.
