Abstract
A reflector of the elastic wave resonator in an elastic wave device has first and second regions. The second region has third and fourth regions. The first region is located near to the IDTs of the reflector, while the second region is located farther from them. The third region is located nearer to the IDTs in the second region, while the fourth region is located farther from them. As a result that the center frequency of the reflection band in the fourth region is lower than that in the third region, an elastic wave device with low energy loss and insertion loss is provided.
