Abstract

A magnetostatic wave device includes a dielectric substrate. Micro strip lines as transducers are formed by forming a ground electrode and strip-line electrodes, on both surfaces of the dielectric substrate. A ferrimagnetic base material formed with a GGG substrate and a YIG thin film on the GGG substrate is arranged on the strip-line electrodes. The ferrimagnetic base material is formed so that the end portions slant from the strip-line electrodes outwardly. The length of the ferrimagnetic base material is established to provide a minimum value.
