Claim Text:
1. A communication terminal device comprising: a casing that includes a leading end portion, a metal portion defining at least a portion of the casing, and a pair of main surfaces; and an antenna that includes a magnetic core including a first main surface and a second main surface, which oppose each other, and a coil conductor that is arranged on at least either of the first main surface and the second main surface of the magnetic core and is arranged adjacent to the metal portion of the casing; wherein the antenna is configured to have directivity direction that is tilted toward a direction of the leading end portion from a direction that is perpendicular or substantially perpendicular to the pair of main surfaces of the casing; the coil conductor includes a first conductor portion positioned on a side of the first main surface of the magnetic core and a second conductor portion positioned on a side of the second main surface of the magnetic core and arranged at a different position than the first conductor portion when viewed in a direction perpendicular to the first and second main surfaces, and the coil conductor is arranged such that the side of the first main surface of the magnetic core is on a side of the magnetic core closer to the metal portion and such that the first conductor portion of the coil conductor faces the leading end portion; and a position in a center of the coil conductor is arranged farther from the leading end portion toward a trailing end portion of the casing, which is an end portion on the side opposite to the leading end portion, than a position in a center of the casing in a longitudinal direction of the casing.
