An assembly structure of a knob for an electric appliance is provided to allow assembling by screw connection with a circuit substrate to which the knob is hook-joined instead of a difficult press process. An assembly structure of a knob for an electric appliance includes a circuit substrate(110), a knob(120), and a joining member(130). The circuit substrate includes a plurality of tact switches(112) at regular intervals and has through-holes(114) at portions close to the tact switches. The knob is inserted into the through hole of the circuit substrate with a hook(122a). The joining member allows the circuit substrate with the knob to be screwed with a joining projection(104) projected from a front panel(100) in order to fix the circuit substrate to the front panel.
