    • A fabrication method of a SAW device. A first conductive layer, an etch-stop layer made of conductive material and a second conductive layer are formed one atop another in their order on the piezoelectric ceramic substrate. A mask is provided on a first portion of the second conductive layer corresponding to a first SAW filter region. A second portion of the second conductive layer corresponding to a second SAW filter region is selectively removed by using the mask. The mask is removed and a photoresist pattern in use for forming electrodes of the first and second SAW filters is provided on the first portion of the second conductive layer corresponding to the first SAW filter region and on a first portion of the etch-stop layer corresponding to the second SAW filter region. The first and second conductive layers and the etch-stop layer are selectively removed by using the photoresist pattern, and the photoresist pattern is removed.
