Abstract
The invention provides a rotation sensor enabling simplification of manufacturing process, such as an inspection step, while maintaining measurement accuracy of the rotation sensor. Lead frames of a rotation sensor have positioning sections which contact a side surface section of a case and, in this state of contact, keep the insertion depth dimension of a magnetism detection unit in the internal space of the case to a prescribed dimension; a flange lower flat surface of a flange section is provided further towards the case bottom surface side than a flange lower flat surface of a ring-shaped rib, a portion of the outer peripheral section of the case and the ring-shaped rib are exposed in a ring shape from an exterior molding section, and the case is provided with a plurality of projections along the inner side surface of the case which constitutes the internal space.
