摘要：
An acoustic boundary wave device includes a first medium having piezoelectricity, electrodes that are provided on the first medium and excite acoustic waves, a second medium made of a material different from the first medium and provided on the first medium so as to cover the electrodes, and a third medium that has a heat conductivity higher than that of the second medium and is provided so as to contact an upper surface of the second medium and at least a part of side surfaces of the second medium.
