A signal line that is easily inflected includes a laminated body including at least insulator layers that include flexible material and are laminated from a positive direction side in a z axis direction to a negative direction side therein in this order. A ground conductor is securely fixed to a main surface on the positive direction side of the insulation sheet in the z axis direction. A signal line is securely fixed to a main surface on the positive direction side of the insulator layer in the z axis direction. A ground conductor is securely fixed to a main surface on the positive direction side of the insulator layer in the z axis direction. The ground conductors and the signal line define a stripline structure. The laminated body is inflected so that the insulator layer is located on an inner periphery side, compared with a location of the insulator layer.

An antenna for a wireless IC device having improved energy transfer efficiency with a wireless IC, and a wireless IC device equipped with the antenna are constructed such that the antenna includes a coil pattern and spiral coupling patterns provided at the ends of the coil pattern and disposed so as to face each other. A coupling module including a wireless IC chip and a feeder circuit substrate including a feeder circuit arranged to be coupled to the wireless IC chip is mounted on the coupling pattern so as to define a wireless IC device. The coil pattern is an open type coil pattern. The coupling patterns are arranged close to each other to define a single LC resonator. Thus, energy is concentrated in the coupling patterns, thereby improving the energy transfer efficiency between the antenna and the wireless IC chip.

A radio frequency IC device includes a radio frequency IC chip, a feeder circuit substrate, and a radiating plate. The feeder circuit substrate includes a feeder circuit that electrically connects to the radio IC chip and that includes a resonance circuit and/or a matching circuit including inductance elements. The feeder circuit substrate is bonded to the radiating plate, which radiates a transmission signal supplied from the feeder circuit and supplies a received signal to the feeder circuit. The inductance elements are arranged in spiral patterns wound in opposite directions and couple to each other in opposite phases. The radio frequency IC device is able to obtain a radio frequency IC device that is not susceptible to being affected by a usage environment, minimizes variations in radiation characteristics, and can be used in a wide frequency band.

According to one embodiment, in a constricted part of a globe, one end is set to a minimum diameter, the other end is set to a maximum diameter, and a diameter thereof increases from the one end side to the other end side. The constricted part of the globe is concaved into the inside of an imaginary straight line connecting an outer edge of the one end and an outer edge of the other end when viewed in section. A light source part includes a semiconductor light-emitting element and is contained in the globe so that a light-emitting part is positioned between both the ends of the constricted part of the globe. A cap is positioned on one end side of the globe.
