1. A grasp detection device comprising:
a measurer configured to measure an electrical characteristic of an electrode provided in a steering handle of a vehicle;
a detector configured to detect grasp of a rim part of the steering handle by a driver based on comparison between an electrical characteristic measurement by the measurer and a grasp threshold; and
a threshold setter configured to set the grasp threshold based on a torque detection value by a torque sensor and the electrical characteristic measurement, the torque sensor being configured to detect steering torque to the steering handle.
