Sensor element, inertial sensor, and electronic apparatus

An electronic apparatus, comprising:

• a sensor element that includes:
• a base portion that includes a main surface,
• a movable portion movable based on reception of an acceleration along at least a uniaxial direction, wherein the movable portion is movable relative to the base portion,
• a first bridge portion that includes:
• a first beam that extends in a first axis direction parallel to the main surface and connects the base portion and the movable portion, and
• a first structure between the first beam and the base portion, wherein the first structure supports the first beam,
• a second bridge portion that includes:
• a second beam that extends in a second axis direction orthogonal to the first axis and parallel to the main surface, wherein the second beam connects the base portion and the movable portion, and
• a second structure between the second beam and the base portion, wherein
• the second structure supports the second beam,
• each of the first beam and the second beam includes:
• a first end portion connected to the movable portion,
• a second end portion connected to the base portion, and
• a joint portion between the first end portion and the second end portion, and
• each of the first structure and the second structure is between the base portion and the joint portion;
• a first acceleration detector unit on each of the first beam and the second beam, wherein the first acceleration detector unit is configured to output a first detection signal that corresponds to an amount of deformation of each of the first beam and the second beam;
• and
• a second acceleration detector unit on each of the first beam and the second beam, wherein the second acceleration detector unit is configured to output a second detection signal that corresponds to an amount of deformation of each of the first beam and the second beam.
