Abstract
A non-reciprocal circuit element includes first, second, and third central conductors, which are formed of thin films or thick films. Each of the first, second, and third central conductors includes a first extended portion which extends from one end of the corresponding central conductor and which is disposed on a side surface of the ferrite part and a second extended portion which extends from the other end of the corresponding central conductor and which is disposed on the side surface of the ferrite part. The adjacent first and second extended portions face each other with a second dielectric part formed of a thin film or a thick film disposed therebetween, and hence a capacitor is formed between the adjacent first and second extended portions. Without using known chip capacitors, the capacitors are thinly formed, leading to reduction in cost and size of the non-reciprocal circuit element.
