To provide a switch device capable of achieving cost reduction, downsizing and simplification.

The switch device 2 is equipped with a substrate 24 in which a wiring pattern is formed, a knob 21 as an operation part having an operation face 210 where push operation and touch operation are carried out, a support member 22 as a first switch part to have a conductive support part 222 to support the knob 21 and to output changes in electrostatic capacity based on the touch operation against the operation face 210 to the wiring pattern, and a push switch 23 as a second switch part which is installed between the substrate 24 and the knob 21 and outputs a signal based on displacement of a push direction of the knob 21 to the wiring pattern.
