A faucet is formed with at least an inner waterway support layer, a middle filling layer, and an outer organic plastic layer. The inner waterway support layer is made of a material without any heavy metal; the middle filling layer wraps around the inner waterway support layer, being formed with an organic plastic and a filler. The faucet is formed with the inner waterway support, in which the support is made of a material without lead. The copper is not applied; even if being applied, the copper is applied in only a middle section of waterway of the faucet. Another low-cost filler is applied in most of the sections of the outer layer, thereby the cost being significantly reduced. The material is poor in heat conductivity and rich in heat insulation, preventing the faucet from scalding a user; the heat loss may be reduced for economy energy and environmental protection.
