A push and rotation operating type electronic component that allows for rotary manipulation in a tangential direction of a peripheral surface of a cylindrical operating knob projecting from a control surface of an apparatus, and also for pushing manipulation in a direction toward a central axis of rotation of the knob. The electronic component provides for a reduction in overall dimensions of a main portion, thereby reducing a height size of an enclosure of the end-use apparatus, smooth movement to a depressing manipulation, and easy to assemble. It is provided with a rotary encoder comprising a cylindrical rotary body with stepped periphery having a cylindrical knob portion of large diameter at a center, and rotatably retained in a frame supported also rotatably on a substrate and flexible contact bars retained by the substrate and in resilient contacts with a movable contact provided on a peripheral surface of a cylindrical axle besides the knob portion, and a push switch of a self-restoring type disposed on the substrate and activated by a turning movement the frame.
