Then, the first circuit board 270 constituting the first detection means (the sliding contact pattern 233) and the second circuit board 210 constituting the second detection means (the sliding contact pattern 183) are laminated in the direction of the rotation axis L. In addition, since the first rotating body 130 is installed in the openings 181 and 191 provided in the second circuit board 210, it is possible to reduce the size of the rotary electronic component 1-1 in the thickness direction.

  Further, since the first and second clutch portions 95 and 93 of the clutch member 90 are formed from both surfaces of the clutch member 90 in the direction of the rotation axis L, the first and second clutch portions 95 and 93 and the first clutch portions 90 and 93 are formed. The second clutch engaging portions 133 and 71 do not expand in the radial direction, and thus the size of the rotary electronic component 1-1 can be reduced in the radial direction.
