PROBLEM TO BE SOLVED: To provide a magnetostatic wave element, capable of making the degree of suppression increase without increasing an insertion loss. SOLUTION: A GGG board 3 is located on a ground substrate 4, YIG films 2a and 2b are located on the GGG board 3 and on the principal side of the YIG films 2a and 2b, ferromagnetic layers 5a-5d are respectively located on both the terminal sides in the lengthwise direction of the YIG films 2a and 2b. Along the lengthwise direction of the YIG films 2a and 2b, a DC magnetic field H is impressed, magnetostatic waves are propagated inside the YIG films 2a and 2b by inputting an input signal from an electrode 1a for input located on the YIG film 2a, and an output signal is provided from an electrode 1b for output located on the YIG film 2b. |
