PROBLEM TO BE SOLVED: To provide a sensor signal processing structure usable in the same signal processing circuit for both cases of a Hall element and a resolver, and capable of acquiring angle information at low cost. SOLUTION: This sensor signal processing structure P10 has a constitution including a circuit P1 for R/D conversion usable for both processings for a Hall element output signal PH and a resolver output signal PR. When either the Hall element output signal PH or the resolver output signal PR is inputted into the structure P10, it is processed by a function possessed by the circuit P1 for R/D conversion included in the structure P10, and a signal S processed by them is generated.
