A mobile terminal device, which is capable of suppressing lowering of a resultant speed when speed data cannot be correctly measured by a rake receiver due to control of AFC or the like, is provided. A comparing section 16 reads a current resultant speed out of a resultant speed storage section 18, and compares the speed data measured by the rake receiver 13 with the current resultant speed. When the speed data is faster than the current resultant speed, the filter section 17 stores the speed data as the resultant speed in the resultant speed storage section 18 as is without performing any filtering process on the speed data measured by the rake receiver 13. When the speed data is slower than the current resultant speed, the filter section 17 averages the speed data measured by the rake receiver 13 and the current resultant speed, and store the averaged speed data as the resultant speed in the resultant speed storage section 18.
