Physical quantity sensor, physical quantity sensor device, composite sensor device, inertial measurement unit, electronic apparatus, and vehicle

A physical quantity sensor comprising:

• a substrate;
• a fixed portion that is fixed to the substrate;
• a movable portion that includes a frame part surrounding the fixed portion in a plan view, is connected to the fixed portion, and is displaceable in a first direction with respect to the substrate;
• and
• a movable electrode that is supported at the movable portion,
• wherein the frame part includes
• a first outer edge that is located on one side of the first direction, and is disposed along a second direction orthogonal to the first direction, and
• a second outer edge that is located on the other side of the first direction, and is disposed along the second direction,
• wherein the fixed portion is disposed further toward the second outer edge than the first outer edge, and
• wherein the substrate includes
• a first projection part that overlaps the first outer edge in a plan view, and is disposed to be separated from the first outer edge, and
• a second projection part that overlaps the second outer edge in a plan view, and is disposed to be separated from the second outer edge.
