Abstract

A manufacturing method is provided for a resonance device that includes preparing a collective board including first power supply terminals electrically connected to upper electrodes of a plurality of resonators, and a first coupling wire that electrically connects two or more of the first power supply terminals. The method includes dividing the collective board into a plurality of resonance devices. Moreover, the first power supply terminals include a first metal layer and a second metal layer covering the first metal layer. The first coupling wire includes a portion of the first metal layer that extends from a region covered with the second metal layer. The method further includes removing the portion of the first metal layer extending from the region covered with the second metal layer before the dividing the collective board into the plurality of resonance devices.
