The antenna patterns 112A of the wiring layers 112 may be disposed on an upper surface of the core layer 111a, and the ground patterns 112G of the wiring layers 112 may be disposed on a lower surface of the core layer 111a. The antenna patterns 112A may be disposed, respectively, on the insulating layers 111b built-up on the core layer 111a. The antenna patterns 112A disposed, respectively, on the insulating layers 111b built-up on the core layer 111a may be disposed directly above or below each other and be coupled to each other. For example, the antenna patterns 112A may form a capacitance. However, a disposition of the antenna patterns 112A may be changed depending on a type of antenna, and the insulating layers 111b may be built-up only beneath the core layer 111a, if necessary. In this case, the antenna patterns 112A formed on the insulating layers 111b built-up on the core layer 111a may be omitted.
