Abstract
An elastic wave device includes a plate-shaped elastic wave element and a resin structure including a high elastic modulus resin portion and low elastic modulus resin portions. The low elastic modulus resin portions are provided in regions of side surfaces of an elastic wave element substrate, which extend from end portions at an IDT electrode formation surface side and do not reach a surface at a side opposite to an IDT electrode formation surface, and a remaining resin portion of a portion of the resin structure, which contacts with the side surfaces of the elastic wave element substrate, is the high elastic modulus resin portion.
