PROBLEM TO BE SOLVED: To provide a non-reciprocal circuit element for preventing a center conductor from rupturing even if reducing the width of the center conductor and fining the center conductor, and to provide a communication device using the non-reciprocal circuit element. SOLUTION: A magnetic rotor 21 has a soft magnetic substrate 210 and first to third center conductors 211-213. The first to third center conductors 211-213 are composed of mutually independent metal plates and are arranged while the metal plates cross mutually on one surface of the soft magnetic substrate 210. A component mount substrate 1 has a conductive substrate 10 and an insulation film 11. The insulation film 11 has ground electrodes 110-116 for exposing the surface of the conductive substrate 10 on at least one surface of the conductive substrate 10, and covers the entire surface of the conductive substrate 10 except the ground electrodes 110-116. The magnetic rotor 21 and circuit components 221-224 are mounted onto one surface of the component mount substrate 1. COPYRIGHT: (C)2008,JPO&INPIT
