To provide an angular velocity sensor capable of preventing a fluctuation in an output while reducing a size and thickness and reducing a cost, and electronic equipment.

Since a beam part 230 bridges over a circuit board part 210 and a relay board part 220 to cause the relay board part 220 to elastically hold the circuit board part 210, external stress can be alleviated and vibration can be shut, thereby preventing the fluctuation in the output. Moreover, since the circuit board part 210, the relay board part 220 and the beam part 230 are constituted of a single board 200, the three components can be made up of the single board 200. Thus the size and thickness can be reduced, and the cost can be reduced.
