Abstract
A GND terminal 74 extends into a package 7, and the inwardly extending portion has a laterally extending portion (lateral portion) and a longitudinally extending portion (longitudinal portion). The lateral and longitudinal portions of the GND terminal 74 form an L-shaped metal portion 80 extending in a recess 78 of the package 7. When accommodating an SAW filter 100 in the package 7, the SAW package 100 is set in the recess 78 of the package 7 such that the back surface of the chip substrate is in contact with the L-shaped portion 80.
