Abstract: An inertial force sensor includes a fixed part, a beam connected to the fixed part, a plummet connected to another end of the beam and being displaceable due to inertial force to cause the beam to deform, a conductive part provided at the plummet, a strain-sensitive resistor provided at the beam for detecting a deformation of the first beam, first and second fault diagnostic electrodes provided at the fixed part, a first fault diagnostic wiring for connecting the first fault diagnostic electrode to the conductive part through the beam, and a second fault diagnostic wiring for connecting the second fault diagnostic electrode to the conductive part through the beam. The inertial force sensor does not continue to output an erroneous output signal when a crack occurs in the plummet, thus having high reliability.
