    Abstract: A bulk-acoustic wave resonator includes a resonator including a central portion in which a first electrode, a piezoelectric layer, and a second electrode are sequentially stacked on a substrate, and an extension portion disposed along a periphery of the central portion; and an insertion layer disposed between the piezoelectric layer and the substrate in the extension portion to raise the piezoelectric layer. The insertion layer includes a first insertion layer having a first inclined surface formed along a side surface facing the central portion and a second inclined surface disposed between the first insertion layer and the piezoelectric layer and having a second inclined surface spaced apart from the first inclined surface with respect to a surface direction of the first electrode. The first insertion layer is thinner than the second insertion layer.
