Abstract
A ceramic capacitor includes: a dielectric layer of which a main component is a ceramic grain, wherein one or more pores are formed inside of the ceramic grains; and wherein an area ratio of the one or more pores with respect to a cross section of the ceramic grain is 0.03% to 0.20%, in a cross section of the dielectric layer.
Claims8
