Intermediate film for laminated glass and laminated glass

Abstract

A wedge shaped interlayer film for laminated glass having good sound insulation performance and having five or more resin layers, including: a first resin layer having a glass transition temperature of 15° C. or higher, a second resin layer having a glass transition temperature of lower than 15° C., a first edge, and a second edge opposite the first edge. A thickness of the second edge is larger than the thickness of the first edge, and when a percentage of a total thickness of second resin layer with respect to the total thickness of all the resin layers is taken to be a layer percentage A (%), and a distance from the first to second edges is taken to be X, the interlayer film has a region of 0.5X in which a difference between a maximum value and a minimum value of the layer percentage A is 10% or less.
