PURPOSE: Provided is a polyurethane foam which has excellent hygroscopicity, deodorizing effect, anti-mould activity, insect resistance, heat insulation and anion emission. CONSTITUTION: The polyurethane foam formed by the reaction of a polyol with an isocyanate is characterized by further comprising a charcoal powder and an anion powder present inside of the polyurethane foam. The polyurethane foam optionally further comprises an antistatic agent. The polyurethane foam is produced by the method comprising the steps of: forming polyol; adding charcoal powder, anion powder and an antistatic agent to the polyol and stirring the mixture; adding isocyanate, water, a catalyst and a surfactant to the polyol to foam the polyurethane; and drying the polyurethane foam naturally and then aging.
