Abstract
Provided is a highly reliable acoustic wave device wherein deterioration of electrical characteristics due to deformation of a protective cover is suppressed. A method for manufacturing such acoustic wave device is also provided. The acoustic wave device has a piezoelectric substratepropagating an acoustic wave; an excitation electrode arranged on a first main surface of the piezoelectric substrate; a columnar outside connection-use electrodeelectrically connected to the excitation electrode; a protective coverhaving a hollow accommodating spacein which the excitation electrode is accommodated on the first main surface; and a conductive layerconnected to the electrodeon the protective cover
