Abstract
An elastic wave device includes a multilayer film provided on a support substrate and including a piezoelectric thin film and a layer other than the piezoelectric thin film, an interdigital transducer electrode provided on one surface of the piezoelectric thin film, and an external connection terminal electrically connected to the interdigital transducer electrode. In a plan view, the multilayer film is partially absent or omitted in a region outside a region where the interdigital transducer electrode is provided, and the elastic wave device further includes a first insulating layer provided on the support substrate in at least a portion of a region where the multilayer film is absent or omitted.
