A vehicular touch pad disposed in a vehicle compartment includes a design panel configuring an outer surface, a capacitive sensor panel disposed below the design panel and including at least two planes having different distances to the design panel, and an arithmetic device. The arithmetic device estimates a proximity degree between a manipulation body and the design panel and a position of the manipulation body relative to one plane having a shorter linear distance to the design panel based on an electric charge stored between the one plane and the manipulation body. The arithmetic device further determines whether the manipulation body touches the design panel based on an electric charge stored between a different plane having a longer linear distance to the design panel and the manipulation body.
