Abstract
An acoustic resonator including a substrate, an active vibration region including, sequentially stacked on the substrate, a lower electrode, a piezoelectric layer, and an upper electrode, and a horizontal resonance suppressing part formed from and disposed in the piezoelectric layer, the horizontal resonance suppressing part having piezoelectric physical properties that are different from piezoelectric physical properties of the piezoelectric layer.
