Disclosed is a phenol resin foam having excellent flame retardance and fire resistance, good heat insulation performance, and excellent physical properties. This phenol resin foam has higher pH than the conventional phenol resin foams, while exhibiting good corrosion resistance to members in contact with the foam. Specifically disclosed is a phenol resin foam obtained by foaming and curing an expandable phenol resin molding material which contains a phenol resin, a foaming agent, a foam stabilizer, a curing agent and an inorganic filler. The foaming agent contains a chlorinated aliphatic hydrocarbon compound having 2-5 carbon atoms, and the molding material contains 70-220 parts by mass of the inorganic filler per 100 parts by mass of the phenol resin. |
