<p>A rotation sensor includes a magnetic sensor array (5) including magnetic sensor elements (19) in line, a rotatable magnet (4) confronting the magnetic sensor array (5), a signal readout circuit (11) for reading out a signal from the magnetic sensor array (5), a repeating section (13) for causing the signal readout circuit (11) to repeat reading out the signal from the magnetic sensor array (5) several number of times, and calculating a summation or an average of several readout signals, and an angle calculating circuit (14) for detecting an angle of rotation of the magnet (4) from the summation or the average of the signals calculated by the repeating section (13).</p> |
