Abstract
An elastic wave device is described which includes a piezoelectric substrate, comb-shaped electrodes having teeth electrodes that are disposed so as to face each other on the piezoelectric substrate, a non-overlapping area in which the teeth electrodes of the comb-shaped electrodes do not overlap each other, and a overlapping area in which the teeth electrodes overlap each other and the velocity of sound is higher than that in the non-overlapping area.
