<p><P>PROBLEM TO BE SOLVED: To realize a personal identification device for easily performing the personal identification of a user. Ž<P>SOLUTION: A vibration part 252 continuously changes a frequency generated by a vibration motor 120 arranged inside a casing 110 of a game controller 10 in such a state that the casing 110 is gripped by a user. A triaxial acceleration sensor 140 and a triaxial acceleration sensor 180 detect the vibration of the vibration motor 120. The frequency components of the detected vibration are extracted by an extraction part 156 and weighted for every frequency component by a data working part 255. A storage part 253 stores the weighted frequency components for every user. A determination part 254 compares and collates the frequency components extracted from measurement data obtained by vibrating the vibration motor 120 in such a state that the casing 110 is gripped by the user with the frequency components of the storage part 253 so as to perform the personal identification.
