Abstract
In examples, there is provided a bulk acoustic wave resonator including a substrate; a resonating part including a first electrode, a piezoelectric layer, and a second electrode, laminated on an upper surface of the substrate, a cap bonded to the substrate by a bonding agent; and a sealing layer formed on an externally exposed surface of the bonding agent. This structure provides for a bulk acoustic wave resonator with improved reliability.
