PROBLEM TO BE SOLVED: To miniaturize and simplify an angle sensor at a low cost by forming a resolver integrally with an incremental encoder by using a fixed disc and a rotary disc. SOLUTION: This angle sensor has a small, flat and inexpensive structure composed by forming the resolver 20 integrally with the incremental encoder 34 by using a fixed slit 2 and a fixed coil pattern 3 for the resolver formed on the fixed disc 1, and a rotary slit 5 and a rotary coil pattern 10 for the resolver formed on the rotary disc 4.
