<P>PROBLEM TO BE SOLVED: To provide a sensor element that is minimally displaced due to an influence of an ambient temperature for accurately detecting minute displacement. <P>SOLUTION: A flat surface portion of a Hall element 12 is adhered tightly onto a cut surface 16 formed on a shaft 11 with an adhesive, so as to support a circuit board 13 in the air by a lead frame 14. Owing to this structure, even when the lead frame 14 or a solder 15 is thermally expanded, or even when the circuit board 13 is deformed, the Hall element 12 is never displaced against the shaft 11 and measurement accuracy for a rotation angle of the shaft 11 is minimally affected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
