COMMUNICATION TERMINAL APPARATUS

摘要

PROBLEM TO BE SOLVED: To configure a communication terminal apparatus capable of suppressing deterioration of communication performance and communicating with a communication partner in a wide angle range irrespective of a spatial relationship (in particular, an angular relationship) with the communication partner.SOLUTION: A ground conductor as a plate-like conductor is provided in an inner layer of a circuit board 20. On a surface and rear face of the circuit board 20, various electronic parts for constituting a mobile communication terminal besides a feeder circuit connected to an antenna coil 21 are mounted. The antenna coil 21 is mounted in a state where a first principal surface MS1 of a magnetic substance core 8 faces the circuit board 20. The antenna coil 21 is arranged so that a first conductor part 11 may be located at a position closer to a ground conductor GND than a second conductor part 12 in a coil conductor 9. The antenna coil 21 is arranged so that the first conductor part 11 of the coil conductor 9 may be located in the vicinity of an end (part which becomes an upper end part in a state where a communication terminal apparatus is grasped in a longwise direction) E in a longitudinal direction of a housing 200.
