Provided are a foamed resin insulation material and a method for manufacturing the foamed resin insulation material that can reduce difference in a linear expansion coefficient between a metal and the foamed resin insulation material, reduce generation of thermal stress in the foamed resin insulation material as much as possible, and can prevent crack formation. The foamed resin insulation material is formed of a resin foam-molded body obtained by foam-molding an unfoamed resin material mixed with a negative thermal expansion material having a volume that is contracted when a temperature rises and is expanded when a temperature falls. Fiber sheets each composed of intersecting warp yarns and weft yarns are integrated with the resin foam-molded body at inner and outer faces.
