摘要:
A Lamb wave type high frequency device comprises: a piezoelectric substrate; an interdigital transducer (IDT) electrode formed on a first main surface of the piezoelectric substrates a reinforcing substrate connected to a second main surface of the piezoelectric substrate; a space portion formed in one of the piezoelectric substrate and the reinforcing substrate, an area of the space portion being larger than a region in which a Lamb wave is propagated; and a connecting surface formed in a periphery of the space portion.
