A wireless IC device includes a wireless IC chip arranged to process a radio signal, a power-supply circuit board that is connected to the wireless IC chip and that includes a power supply circuit including at least one coil pattern, and a radiation plate arranged to radiate a transmission signal supplied from the power-supply circuit board and/or receiving a reception signal to supply the reception signal to the power-supply circuit board. The radiation plate includes an opening provided in a portion thereof and a slit connected to the opening. When viewed in plan from the direction of the winding axis of the coil pattern, the opening in the radiation plate overlaps with an inner area of the coil pattern and the area of the inner area is approximately the same as that of opening.

A front-end circuit includes a multiplexer, a circulator, reception ports, and variable filters. A port in the multiplexer is connected to an antenna. A port in the circulator is connected to a port in the multiplexer. The reception ports are connected to a port in the circulator with the variable filters interposed therebetween. The multiplexer outputs a communication signal having a frequency in a low band to the port and outputs a communication signal having a frequency in a middle band to a port. Each of the low band and the middle band includes a plurality of frequency bands. The middle band is a range of frequencies higher than those in the low band and does not overlap the low band.

A ceramic substrate for an electrochemical element that includes a ceramic layer and a high-thermal-expansion-coefficient material layer that is laminated on the surface of the ceramic layer. The high-thermal-expansion-coefficient material layer has a higher coefficient of thermal expansion than the ceramic layer, and applies compressive stress to the ceramic layer.
