Abstract: A chip antenna that is simple in structure, produces small variation in antenna characteristics between individual antennas, and requires no circuit adjustments, is excellent in productivity. The chip antenna is capable of being mounted on a circuit board, as well as a wireless terminal using the chip antenna. A method of fabricating the chip antenna. A core body is made from an insulating material in a quadrangular or circular cylinder shape. A conductor in a helical shape is mounted on the side surface of the core body. A terminal portion is provided on the core body and electrically connected with an end portion of the conductor. The width, depth, and length of the core body are within ranges of 0.5-5 mm, 0.5-5 mm, and 4-40 mm, respectively. Intrinsic volume resistance and relative dielectric constant of the material are 1013 ?·m or above and 40 or below, respectively.
