Abstract: A portable terminal device including a main body including a data entry keyboard; a cover openably and closably attached to the main body and establishing a connecting portion between the main body and the cover; a display disposed on the inner side of the cover; a chip antenna disposed on the cover at a place other than the display and opposed to the connecting portion; the chip antenna including a ceramic base body, a conductor disposed at least either inside the base body or on a surface thereof, and a feeding terminal disposed on a surface of the base body and connected to one end of the conductor. The above portable terminal device has the directivity of an antenna in a desired direction without increasing the size and weight of the portable terminal device and without having a bulky and/or separate and/or protruding antenna device.

Abstract: A chip antenna comprising a basic body made of a ceramic material; a first conductor and a second conductor respectively disposed at least either inside or on the surface of the basic body so as to be close to each other; a feeding terminal for applying a voltage to the first conductor disposed on the surface of the basic body and connected to the first conductor; and a grounding terminal disposed on the surface of the basic body and connected to the second conductor.
