FIG. 11 is a graph showing the results of the electromagnetic field simulation conducted on the inductors pertaining to Example 2, Comparative Example 1, Comparative Example 2, and Comparative Example 3. In FIG. 11, the horizontal axis represents the inductance value at 500 MHz, while the vertical axis represents the Q-value at 1800 MHz. It should be noted that the simulation was conducted on the inductors in Example 2, Comparative Example 1, Comparative Example 2, and Comparative Example 3, which had the same dimensions explained using FIG. 6 in Example 1. As shown in FIG. 11, the Q-value was higher in Example 2 than in Comparative Examples 1 to 3. The Q-value of the inductor 200 in Example 2 became higher probably because of the same reason explained in Example 1. To be specific, the smaller parasitic capacitance due to the lead conductor parts 38, and the coupling of the magnetic fields generated by the currents flowing through the coil conductor 36 and the external electrodes 50, probably caused the Q-value to become higher.
