PROBLEM TO BE SOLVED: To provide glass interleaving paper eliminating the need for strict adjustment of a basis weight, a wood type of raw pulp and the like, having a good upright property corresponding to enlargement, and also having stability so that a curl is hard to be deformed due to moisture change, and a laminate using the same.SOLUTION: There is provided glass interleaving paper obtained by papermaking a raw material containing a pulp fiber as a main component. The paper is obtained by papermaking the material by a Fourdrinier method and then subjecting the resulting material to a flat treatment by using a calender. The paper has bulk density of 0.6 g/cmor more and 1.2 g/cmor less. It is preferable that freeness of disaggregated pulp is 400 mL or more and 650 mL or less, and a fibrillation ratio is 2.5% or more and 4.5% or less. It is preferable that the disaggregated pulp contains needle bleached kraft pulp (NBKP) and leaf bleached kraft pulp (LBKP), and a weight ratio of the NBKP and the LBKP is 2:98 or more and 20:80 or less. |
