Resonator and resonance device

A resonator comprising:

• a vibrating portion including:
• three vibrating arms each having a fixed end, wherein at least two vibrating arms of the three vibrating arms are configured to bend out of plane with different phases, and
• a base portion having a first end coupled to the fixed end of each of the three vibrating arms, a second end opposed to the first end, and a side end;
• a holding portion configured to hold the vibrating portion;
• and
• a support arm comprising a first end connected to the holding portion and a second end connected to the side end of the base portion,
• wherein the support arm extends from a first side to a second side with respect to a center line of the vibrating portion with respect to a longitudinal direction in a plan view, and the second end of the support arm is connected to the side end on the second side on the base portion.

A resonance device comprising:

• a resonator including:
• a vibrating portion including:
• a plurality of vibrating arms each having a fixed end, wherein at least two vibrating arms of the plurality of vibrating arms are configured to bend out of plane with different phases, and
• a base portion comprising a first end coupled to each fixed end of the plurality of vibrating arms and a second end opposed to the first end;
• a holding portion configured to hold the vibrating portion;
• and
• a support arm comprising a first end connected to the holding portion and a second end connected to the second end of the base portion,
• wherein the support arm consists of a single arm that is asymmetric with respect to a center line of the vibrating portion with respect to a longitudinal direction in a plan view.
