Surface acoustic wave device and manufacturing method of the same

摘要

A surface acoustic wave device has a SAW device element 10 and a package 20 housing the SAW device element. The package includes a resin substrate 20 having metal patterns 21 and 22 formed on both surfaces thereof, and a resin cap 32. The SAW device element is mounted on one of the metal patterns of the resin substrate. The resin cap is adhered to the resin substrate to cover the SAW device element. The surfaces of the resin substrate are flush with corresponding end surfaces of the resin cap.
