The capacitive sensor apparatus includes: a sensor element disposed on the first surface of the mounting member; and a floating conductor that is disposed on the second surface of the mounting member and is electrically conductive, the floating conductor being electrically disconnected from the sensor element. The sensor element includes: a first electrode; and a second electrode in a shape of a ring surrounding an outer periphery of the first electrode and being electrically disconnected from the first electrode. The floating conductor overlaps at least the first electrode in a projection view seen from the first surface.
