Abstract: According to an aspect, a detection device includes a pattern detector, a force detector, and a controller. The controller is configured to store reference data in advance, acquire new data, and determine whether an object pressed against a contact surface when the new data is acquired is a human finger based on difference between acquisition target data indicated by the reference data at a plurality of timings and the acquisition target data indicated by the new data at a plurality of timings. The timings are two timings or more that are included in a pressing operation period from start to end of pressing of an external object against the contact surface, and the force detected by the force detector is different between the timings.
