PROBLEM TO BE SOLVED: To provide a knob structure of an electronic component, in which a correction instruction during manufacture of mold for a resin knob can be done precisely and strict mold accuracy can be obtained. SOLUTION: An electronic component provided with a rotatable D-shaped shaft 2, a notch rib 11 in contact with a notch 2a of the D-shaped shaft 2 in the knob structure of the electronic component in which an axial cylinder part 5 of a resin knob 3, is engaged with the D-shaped shaft 2, and a directly facing rib 12 that is in contact with the circumferential surface 2b of a circular arc of the D-shaped shaft 2 opposite to the rib 11 in the radial direction, are projected to the inner circumferential surface of the axial cylinder part 5.
