To provide an antenna unit capable of reducing interference of an electric noise or the like with an earth line plate without decreasing the antenna gain even when an entire mobile communication terminal acts like an antenna and to provide the mobile communication terminal provided with the antenna unit.
The antenna unit 10 is configured such that an antenna holder 30 for fixing the antenna unit 10 to an enclosure of the mobile communication terminal is provided with the earth line plate 20 and an earth line contact pin 21 to connect the earth line plate 20 to an earth pattern of a printed circuit board 5, the earth line plate 20 is connected to the earth pattern 5b at a position close to a feeding pin 11 while the antenna unit 10 is contained in the enclosure of the mobile communication terminal, and the earth line plate 20 is located at a position apart from the printed circuit board 5 while providing an installation space for the antenna unit 10 between the earth line plate 20 and the printed circuit board 5.
