The present invention provides: a melamine resin foam obtained by foaming a resin composition comprising a melamine/- formaldehyde condensate, a blowing agent and an isocyanate, a process for producing the above melamine resin foam, which comprises foaming a resin composition comprising a melamine/- formaldehyde condensate, a blowing agent and an isocyanate, and a melamine/formaldehyde condensate useful in the production of the above melamine resin foam, which is obtained by reacting melamine and formaldehyde in the presence of a silane coupling agent. The melamine resin foam is free from the problems of the prior art e.g., fragility without impairing the good flame retardancy and low thermal conductivity inherently possessed by melamine resin foams, and causes no danger during the production.
