Abstract
An SAW device includes a glass substrate, an LiNbO,(LN) substrate, and an electrode. When a pitch of the electrode is &lgr;, a thickness of the LN substrate is H, and K equals to 2&pgr;/&lgr;, a product of K and H is at least 0.5 and at most 1.0. Accordingly, an SAW device is obtained which is provided with high K,and an enhanced temperature characteristic and which can be advantageously reduced in size.
