ABSTRACT:
An electronic component comprising at least one piezoelectric resonator and a process for mass production thereof include the superpositioning of n (n.gtoreq.1) layers having one or several cut outs defining m (m.gtoreq.1) resonating elements. Such layers are separated by n-1 intermediate layers in which are provided openings forming frames for the resonating elements. Two terminal layers providing covers in which are arranged blind cavities corresponding to the frames cover the assembly. The resonating elements are provided with electrodes and the layers are fixed to one another by welding together of metallization layers. The component may be used as an individual resonator or as a multiple channel filter.
