Abstract
The present invention is a phenolic resin foam board having a thickness of 40 mm or more to 300 mm or less, when the phenolic resin foam board is sliced into n pieces (n≥5) at approximately equal intervals of 8 mm or more to 10 mm or less, a density of an n-th specimen is dn, an average density of n pieces of specimens is dave, a lowest density among the densities of n pieces of specimens is dmin, 0≤(dave−dmin)/dave≤0.12 is established, and when values for Di=(di+d(i+1))/2 are calculated, Di values are plotted and points corresponding to the Di values are connected, resulting in a density distribution curve, no straight line parallel to the horizontal axis intersects the density distribution curve at four points.
