Abstract
A hands-on detection device of a steering wheel according to one embodiment of the present invention is a hands-on detection device of a steering wheel comprising: a core metal; a shield electrode provided outside the core metal and separated by an insulator (In); a sensor electrode further provided outside the shield electrode and separated by an insulator (In); and a control unit configured to acquire the capacitance value of the sensor electrode in a state in which the shield electrode and the core metal are short-circuited, and determine whether or not there is a failure based on the capacitance value.
