PROBLEM TO BE SOLVED: To provide a non-reciprocal circuit component and a communication device in which reliability in the connection of a center electrode and a side electrode is high and reduction in the height of a product is not disturbed. SOLUTION: In the order of lamination on an upper surface of a ferrite 20, in both terminal portions of a center electrode 22 in the first layer, electrode thickness is enlarged by charging electrodes 24a, 25a formed within openings 50a, 51a of insulating films 50, 51 formed on the side of an upper surface of both the terminal portions of the center electrode 22 in the first layer. In both terminal portions of a center electrode 21 in the second layer, electrode thickness is enlarged by a charging electrode 25b formed within an opening 51b of an insulating film 51 formed on the side of an upper surface in both the terminal portions of the center electrode 21 in the second layer. In both terminal portions of a center electrode 23 in the final layer (the third layer), electrode thickness is enlarged by charging electrodes 24b, 25c formed within an opening 51c of the insulating film 51 formed on the side of a lower surface in both the terminal portions of the center electrode 23 in the final layer.
