Abstract
A ceramic capacitor includes: a first conductive pattern; a second conductive pattern and a dielectric layer, the first conductive pattern and the second conductive pattern being made of a conductor and provided so as to oppose each other and sandwich the dielectric layer therebetween. The first conductive pattern and the second conductive pattern are different in area from each other, where the second conductive pattern is smaller than the first conductive pattern, and a portion where the first conductive pattern and the second conductive pattern overlap each other forms a capacitance portion. A first extended portion and a second extended portion made of the conductor are formed at both edges of the second conductive pattern so as to extend in mutually opposite directions. With this configuration, the ceramic capacitor with a reduced variation in capacitance value caused by displacement in lamination of green sheets can be provided.
