1. An interlayer film for laminated glass having a one-layer or two or more-layer structure, comprising:
a first layer containing a thermoplastic (meth)acrylic polymer,
wherein the interlayer film for laminated glass satisfies at least one configuration selected from the group consisting of a Configuration (A), a Configuration (B), a Configuration (C) and a Configuration (D), as follows:
Configuration (A): the thermoplastic (meth)acrylic polymer contained in the first layer is a thermoplastic (meth)acrylic polymer having a gel fraction of 5% by weight or less;
Configuration (B): the thermoplastic (meth)acrylic polymer contained in the first layer is a thermoplastic (meth)acrylic polymer having a molecular weight distribution ratio of weight average molecular weight to number average molecular weight of 1 or more and 6 or less, and a gel fraction of 10% by weight or less;
Configuration (C): the thermoplastic (meth)acrylic polymer contained in the first layer is a thermoplastic (meth)acrylic polymer having a molecular weight distribution ratio of weight average molecular weight to number average molecular weight of 1 or more and 6 or less, and the thermoplastic (meth)acrylic polymer contained in the first layer is a polymer contained in a cured product obtained by curing a polymerizable composition containing a (meth)acrylic monomer and a photopolymerization initiator by irradiation with an active energy ray;
Configuration (D): the thermoplastic (meth)acrylic polymer contained in the first layer is a thermoplastic (meth)acrylic polymer having a gel fraction of 5% by weight or less, and the thermoplastic (meth)acrylic polymer contained in the first layer is a polymer contained in a cured product obtained by curing a polymerizable composition containing a (meth)acrylic monomer and a photopolymerization initiator by irradiation with an active energy ray.
