Owing to this, induced electromotive forces generated in the respective areas A1 and A2 when a magnetic flux penetrates the first area A1 and the second area A2 cancel each other, so that an electrical signal output from the magneto-electric conversion element 21 is less influenced by the induced electromotive force. It is, therefore, possible to reduce an error in the electric signal output from the magneto-electric conversion element 21 to the processing circuit section 31.
