Interlayer film for laminated glass, and laminated glass

An interlayer film for laminated glass, the interlayer film comprising:

• one end and the other end being on an opposite side of the one end, the one end having a thickness of 1.05 mm or less;
• a first resin layer having a glass transition temperature of less than 15° C.;
• a second resin layer having a glass transition temperature of 15° C. or more;
• and
• a region where a total number of laminated layers of the first resin layer and the second resin layer in a thickness direction is five or more and ten or less,
• the region where the total number of laminated layers is five or more and ten or less, the region having Y1/Z being 3.67 or more and 6.19 or less when a thickness by one layer of surface layers is denoted by Y1 μm and a thickness by one layer of layers neighboring the surface layers is denoted by Z μm,
• wherein the interlayer film has a length L from the one end and the other end of the interlayer film and the length L is 0.5 m or more, and
• wherein, when an average thickness of a layer other than surface layers in a region from a position of 50 mm to a position of 150 mm from the one end of the length L of the interlayer film is denoted by Y5 μm and an average thickness of a layer other than surface layers in a region from a position of 50 mm to a position of 150 mm from the other end of the length L of the interlayer film is denoted by Y6 μm, Y6/Y5 is 1.20 or more and 2.5 or less.
