A single chip multiple range pressure transducer device including a wafer having a plurality of simultaneously formed thinned regions. Subsequently a sawing operation divides the lead lands into multiple leads, and the leadframe and resin material are partitioned to form packages. Then, a dividing operation is performed on the frequency-domain initial target impulse response and the modified CIR to determine an initial value of the frequency-domain TEQ impulse response. The body portions are flat so that a direction of extension of the flat shape is along a rotational axis direction, and the magnetic member has a U shape as viewed from the rotational axis direction.
