PROBLEM TO BE SOLVED : To provide a dielectric porcelain which maintains high dielectric constant even when its crystal particles are made fine, has a dielectric constant with a small temperature dependency, and is free of chipping; a laminated electronic component using the dielectric porcelain; and a production method for the laminated electronic component. SOLUTION : The dielectric porcelain consists of a grain boundary phase and main crystal particles composed of a perovskite-type compound oxide at least containing Ba, Ti, a rare earth element, Mg, and Mn as metal elements; the content of Al in terms of oxide in the main crystal particles is 0.01 mass% or lower and that in the grain boundary phase is 0.05-2 mass%.
