A grasp detection device 6 includes: a capacitance measurer 68 configured to measure a capacitance of an electrode 60 provided in a steering handle 2 of a vehicle; a grasp detector 70 configured to detect grasp of the steering handle by a driver based on comparison between a capacitance measurement Ch_d by the capacitance measurer 68 and a grasp threshold Ch_thr; and a threshold setter 69 configured to set the grasp threshold Ch_thr based on a torque detection value Tr_d by a torque sensor 31 and the capacitance measurement Ch_d, the torque sensor 31 being configured to detect steering torque. The threshold setter 69 sets the grasp threshold Ch_thr based on the torque detection value Tr_d and the capacitance measurement Ch_d at the time when the vehicle is in a specific driving state, and the torque detection value Tr_d exceeds a torque threshold.
