Abstract
An elastic wave filter includes an electrode finger group in an input side electrode and an electrode finger group in output side electrode each disposed in a taper shape such that elastic waves with mutually different wavelengths propagate on a piezoelectric substrate across from a track Tr1 at a low frequency side of a passband to a track Tr2 at a high frequency side of the passband. Assuming that a period length P is a wavelength of the elastic wave propagating on the piezoelectric substrate and constituted of a width dimension of the finger and a separation dimension between the adjacent electrode fingers, at least one of the input side IDT electrode and the output side IDT electrode includes a specific configuration.
