PROBLEM TO BE SOLVED: To provide a transparent gas barrier laminated film preferably used when a high gas barrier property is necessary. SOLUTION: The gas barrier laminated film is obtained by laminating a gas barrier layer 2, a gas barrier coated layer 3, a gas barrier layer 4 and a gas barrier coated layer 5 orderly on a surface of a base material layer 1. The gas barrier layers 2 and 4 are composed of silicone oxide. The gas barrier coated layers 3 and 5 are made by applying and drying coating liquid containing at least one of a silicone compound represented by a general formula (1) Si(OR<SP>1</SP>)<SB>4</SB>and its hydrolysate, at least one of a silicone compound represented by a general formula (2) (R<SP>2</SP>Si(OR<SP>3</SP>)<SB>3</SB>)<SB>n</SB>and its hydrolysate (R<SP>1</SP>and R<SP>3</SP>each represent CH<SB>3</SB>, C<SB>2</SB>H<SB>5</SB>or C<SB>2</SB>H<SB>4</SB>OCH<SB>3</SB>; R<SP>2</SP>represents an organic functional group; and n is an integer of≥1), and a water-soluble polymer having a hydroxy group.
