| 主权项 | 1. An acoustic wave device, comprising: a support substrate composed of lithium tantalate in multi-polarization condition; an element substrate that is provided on an upper face of the support substrate and is composed of lithium tantalate, a lower face of the element substrate being joined to the upper face of the support substrate; and a comb-like electrode that is provided on an upper face of the element substrate and excites an acoustic wave, wherein domains that voluntarily polarizes are arrayed in the support substrate in random order. | ||
