PROBLEM TO BE SOLVED: To provide a collation device and an electronic signature authentication method capable of improving accuracy of individual authentication in an electronic signature.SOLUTION: A collation device 1 comprises a touch pen 2 and a terminal device 5. The terminal device 5 includes an inclination angle sensor 11 for detecting an inclination angle of an input surface 4a, and an inclination angle data generator 12 for generating inclination angle time sequential data which is the data indicating the time change of the inclination angle during an input period, on the basis of the inclination angle detected by the inclination angle sensor 11. A determination part 15 included in the terminal device 5 compares inclination angle time sequential registration data and the inclination angle time sequential data, and determines whether or not registered signature data and input signature data match. |
