DEVICE FOR DETECTING ROTATION ANGLE

PROBLEM TO BE SOLVED: To make manufacturing cost low in manufacturing of a device for detecting a rotation angle that is mounted in a throttle valve device to detect an opening degree of a throttle valve.SOLUTION: Terminal bodies 42, 52 and connector portions 45, 55 are separately molded when the terminal bodies 42, 52 connected to magnetic detection members or a drive motor and the connector portions 45, 55 connected to external connectors are molded. Thus, the terminal bodies 42, 52 are molded from copper material having spring property and the connectors 45, 55 are molded from brass. The terminal bodies 42, 52, and the connectors 45, 55 can integrally connect to each other via electrically jointing connection portions 48, 58 after the terminal bodies 42, 52 and the connector portions 45, 55 have been molded. A plate thickness of the terminal bodies 42, 52 is set to be 0.4 mm and a plate thickness of the connectors 45, 55 is set to be 0.6 mm.
