ABSTRACT:
A nonreciprocal circuit device and a communication device having a nonreciprocal circuit device in which each end portion of each center electrode in the bottom layer of a multilayer-electrode structure on a surface of ferrite is thickened by forming a filled-in electrode in an opening in first and second insulating films on the upper surface of the end portion of the center electrode in the bottom layer. Each end portion of each center electrode in the second layer is thickened by forming a filled-in electrode in an opening in the second insulating film on the upper surface of the end portion of the center electrode in the second layer. Each end portion of each center electrode in the top layer (third layer) is thickened by forming a filled-in electrode in an opening in the second insulating film on the lower surface of the end portion of the center electrode in the top layer.
