Abstract (en)
There is provided an inductor (1) having a low direct-current resistance and a high Q value. On the surfaces of insulating sheets (11), spiral-shaped coil conductor patterns (3,4) are each formed. Each of the coil conductor patterns (3,4) is set so that the pattern widths of the central portion (j) and the outside portion (k) of the spiral are larger than the pattern width of the inside portion (i) thereof. <IMAGE>
