PROBLEM TO BE SOLVED: To provide a touch pad with an antenna capable of performing accurate position detection by making it possible to reduce influence of driving the antenna on detection of electrostatic capacity.SOLUTION: A touch pad with an antenna 10 comprises: an electrode 13; control means 15 for detecting access of an object and its access position on the basis of change of electrostatic capacity caused by the object's access to the electrode 13; an antenna 14; and antenna drive means 20 for supplying power to the antenna. The control means 15 performs drive control on the antenna drive means 20 so as to make output of the antenna 14 be output in a normal drive time, when not detecting the access of the object; and performs drive control on the antenna drive means 20 so as to make the output of the antenna 14 be attenuated more than the output in the normal drive time or be zero, when detecting the access of the object. |
