1. A phenolic resin foam laminate board in which a surface material is arranged on at least one of one side of a phenolic resin foam and a back side of the one side, wherein:
the phenolic resin foam has a density of not less than 22 kg/m3 and not more than 50 kg/m3, a cell diameter of not less than 50 μm and not more than 170 μm, and a closed cell ratio of not less than 80%;
when HCFO-1224yd(Z), aliphatic hydrocarbons having a carbon number of 6 or less, chlorinated saturated hydrocarbons having a carbon number of 5 or less, and hydrofluoroolefin are gas components, only HCFO-1224yd (Z) is contained as the gas component; and
a cell internal pressure of air bubble is 0.20 atm or more.
