Abstract
A grip detection device comprises an electrostatic capacity sensor mounted on a rim of a steering wheel; and a determination unit that detects gripping of the steering wheel based on a detection result of the electrostatic capacity sensor, a plurality of electrode units of elongated shape configuring the electrostatic capacity sensor extending along a direction in which the rim extends and being provided in parallel along a circumferential direction of the rim, of the plurality of electrode units, at least two electrode units are commonly connected, and at least one electrode unit not commonly connected to the commonly connected two electrode units is disposed between the commonly connected two electrode units, the determination unit determining that a driver has gripped the steering wheel when proximity of a human body has been detected by each of at least two electrode units not commonly connected to each other.
