PROBLEM TO BE SOLVED: To provide a phenolic resin foam capable of maintaining heat insulation performance stably for a long period of time and capable of suppressing the occurrence of metal corrosion when in contact with a metal material. SOLUTION: A phenol resin foam obtained by foaming and curing a foamable phenol resin composition containing a phenol resin, a foaming agent, an acid catalyst and an inorganic filler, wherein the foaming agent has 1 to 8 carbon atoms. The inorganic filler is a filler selected from at least a metal hydroxide, a metal oxide, a metal carbonate and a metal powder, and the pH of the phenol resin foam is 5 or more. And a phenolic resin foam. [Selection figure] None |
