Abstract: A rotary electronic component includes a base member, a shaft attached to the base member so as to be rotatable around an axis, and a regulating member that regulates a rotation angle of the shaft. The shaft includes a flange section including a projecting sections and recessed sections alternately disposed in a circumferential direction. The regulating member includes a contact member in contact with the projecting sections and the recessed sections of the flange section of the shaft, and a biasing member that biases the contact member radially inwardly toward the shaft.

Abstract: A rotary variable resistor includes an insulating substrate, a resistor pattern and a current collector pattern that are provided on the insulating substrate, a rotor that is mounted on the insulating substrate in a rotatable manner, and a slider that is mounted on the rotor and makes sliding contact with the resistor pattern and the current collector pattern to cause the resistor pattern and the current collector pattern to be conducted to each other. When a maximum dimension of the resistor pattern, which defines a variable resistor, is Z [mm] and electric linearity is L [%], Z≦4.0 and Z×L
