1. A rotary electronic component, comprising:
a rotor;
a case portion that rotatably houses the rotor;
an electrode substrate having an annular electrode concentric to a rotation axis of the rotor so that the annular electrode faces the rotor;
a slider provided on the rotor so as to be contacted and conducted with the annular electrode, wherein
the slider includes: a sliding portion having an arc shaped portion protruded toward the electrode substrate so as to be contacted and conducted with the annular electrode; a fixing portion fixed to the rotor; and a connection portion connecting the sliding portion with the fixing portion,
the connection portion and the fixing portion are curved toward the electrode substrate in a predetermined angle,
a buffer member having a flexibility and a water absorbability is provided between the sliding portion and the rotor,
a contact area between the buffer member and the sliding portion is from a tip portion of the arc shaped portion of the sliding portion to an intermediate portion of the arc shaped portion of the sliding portion,
the buffer member is longer than the tip portion of the sliding portion,
the buffer member is not provided between the arc shaped portion and the electrode substrate, and
the buffer member energizes the sliding portion to the annular electrode for suppressing a vibration of the slider.
