An absolute encoder suitable for size reduction is provided. An absolute encoder includes: a first driving gear configured to rotate according to rotation of a spindle; a first driven gear having a center axis perpendicular to a center axis of the first driving gear and configured to engage with the first driving gear; and a second driving gear provided coaxially with the first driven gear and configured to rotate according to rotation of the first driven gear. The absolute encoder includes a permanent magnet () provided on a layshaft gear (A) having a center axis perpendicular to the center axis of the first driven gear and where a worm wheel portion () is formed to engage with the second driven gear; and a resin sheet (A) provided on the layshaft gear (A) to prevent the permanent magnet () from coming out from the layshaft gear (A) in the axial direction.
