Abstract

The present invention relates to wood pulp for glass plate-interleaving paper in which an amount of silicone contained in the wood pulp is 0.5 ppm or less with respect to an absolute dry mass of the pulp, as well as relates to interleaving paper for glass plates of which a raw material is the wood pulp, in which an amount of silicone contained in paper is 0.5 ppm or less with respect to the absolute dry matter of paper. The interleaving paper for glass plates formed from the wood pulp of the present invention, as well as interleaving paper for glass plates of the present invention are able to remarkably control contamination of silicone to the surface of glass plates for use as substrate material for flat panel displays for which a high degree of cleanliness and high quality are required.
