Operation device and operation member

An operation device comprising:

• a housing including an electrically conductive portion formed on at least a portion of a surface thereof;
• an operation lever that is supported by the housing such that the operation lever is tiltable in at least a forward-backward and a left-right direction in response to an operation by an operation body, and that is configured to be capacitively coupled to the operation body and to the electrically conductive portion, the operation lever including
• a shaft that protrudes upward from the housing, and
• an operation knob that is attached to the shaft;
• and
• a detector configured to detect whether the operation body is in proximity to the operation member based on a change in capacitance at the electrically conductive portion, wherein
• the operation knob includes an operation portion configured to be operated by the operation body, and includes an umbrella portion that
• curves outward;
• extends downward from the operation portion;
• and
• surrounds an outer periphery of the housing, and
• an electrically conductive layer is provided on at least a portion of a surface of the operation portion and of the umbrella portion such that the entire surface of the operation lever is electrically conductive.
