摘要

A rotational position detector according to the present invention includes housing (6), a rotor, stator core (1), insulators (2), and transformer core (5). Housing (6) has a cylindrical shape having center axis (14), and inner peripheral surface (6a) extending along center axis (14). Stator core (1) is housed in housing (6) and has outer surface (1c) facing inner peripheral surface (6a). Inner peripheral surface (6a) and outer surface (1c) are located with gap (18) therebetween in a range of not smaller than 50 µm and not larger than 150 µm. In gap (18), anaerobic adhesive (7) is disposed.
