摘要：Low-loss printed circuit boards, low-loss wide-band antennas, and

manufacturing methods thereof are provided by using a resin as a boardmaterial.

Aresinmaterial (101) having a predetermined shape is prepared in a molding step, and theresin material (101) is foamed in a foaming step. As a result, a skin layer (111) and afoamed part (112) are formed. Since the skin layer (111) does not allow close contact ofplating, the skin layer (111) is removed in the shape of a conductor pattern in a skin-layerremoving step to expose the foamed part (112) in the interior. Electroless plating iscarried out in a conductor-layer forming step; and, as a result, plating is brought intoclose contact with the foamed part (112) having an anchor effect, and a conductor layer(120) is formed.
