Abstract

A multilayer resonance device of the invention includes regularly stacked layers each formed by alternately stacking a magnetic substance and a dielectric substance with thickness regularity, and an irregular layer including a magnetic substance, having a thickness disaccording with the thickness regularity and disposed between the regularly stacked layers. Thus, the multilayer resonance device can attain a large Faraday rotation angle, a large magneto-optical effect, and a practical total layer thickness.
