Claim 0:
1. A resonance device comprising:
a resonator including a vibration body and a frame disposed around at least a part of the vibration body, the frame including a holding body and an insulating film having an inner side surface that faces the resonator and extends in a thickness direction of the resonance device, with the holding body holding the vibration body, and with the insulating film disposed above the holding body; and
a first substrate coupled to the frame and having a recess that forms at least a part of a space in which the vibration body vibrates in operation, the space defined by a side wall that extends in the first substrate and defines a stepped planar surface that extends to the frame,
wherein the inner side surface of the insulating film is a first distance outside from an inner surface of the side wall defining the recess, such that the frame does not overlap or coincide with the side wall of the recess in the thickness direction.
