A mold release agent composition, or adhesive, capable of permanent mold release of a board containing any of lignocelluloses and an inorganic material easily from a hot platen in thermocompression molding, excelling in not only mold release capability and productivity but also heat resistance realizing an extremely low possibility of thermal deterioration on the hot platen; and a process for producing therewith a board through thermocompression molding of a molding material containing any of lignocelluloses, which board excels in secondary processability, water absorption swell ratio and flexural modulus. The mold release agent compositionis characterized by containing (I) polyester compound produced through reaction of (A) polyhydric alcohol, (B) dibasic acid and (C) saturated fatty acid in a molar proportion such that (A):(B):(C) = 1 : 0.5 to 1 : 2 to 3 and (II) low-density polyethylene in a weight ratio such that (I):(II) = 1:4 to 4:1.
