    摘要： 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&OHgr;·m or above and 40 or below, respectively.

    摘要： A filter includes a substrate with a relative dielectric constant of 200 or less and a thickness of 0.1 mm or more. A first electrode is disposed on at least one surface of the substrate, a group of second electrodes is disposed on at least the other surface of the substrate. Each of the second electrodes is not in contact with each other and is not in contact with the first electrode. The filter also includes a chip type inductance element. The chip type inductance element has an inductance ranging from 0.1 nH to 30 nH and has dimensions of L1 in length, L2 in width and L3 in height, which satisfy the following conditions; 0.3 mm
