description	PROBLEM TO BE SOLVED: To improve antenna characteristics of a mobile terminal having a built-in antenna provided in a housing and a rod antenna capable of being pulled out from or retracted into the housing.SOLUTION: A mobile terminal comprises: a housing 10b; a built-in antenna 2c provided in the housing 10b; a rod antenna 1a provided capable of being pulled out from or retracted into the housing 10b; and a base plate (ground part) 3 provided in the housing 10b. In a state where the rod antenna 1a is housed in the housing 10b, the rod antenna 1a is connected to the base plate (ground part) 3, and a distance from a power feeding part 2b of the built-in antenna 2c and the rod antenna 1a is within a quarter of an operation frequency band of the built-in antenna 2c.
