An interlayer film for laminated glass according to the present invention includes a first heat-shielding layer and at least one second heat-shielding layer. The first heat-shielding layer includes a thermoplastic resin and at least one component selected from a phthalocyanine compound, a naphthalocyanine compound, and an anthracocyanine compound. The second heat-shielding layer includes a thermoplastic resin and metal oxide particles. The laminated glass of the present invention includes a first member for laminated glass, a second member for laminated glass, and an interlayer film sandwiched between the first member for laminated glass and the second member for laminated glass. The interlayer film is the interlayer film for laminated glass according to the present invention. ## Claims ### Claim 1 An interlayer film for laminated glass, comprising a first heat-shielding layer containing a thermoplastic resin and at least one component selected from a phthalocyanine compound, a naphthalocyanine compound, and an anthracocyanine compound, and at least one second heat-shielding layer containing a thermoplastic resin and metal oxide particles. ### Claim 2 (depends on 1) The interlayer film for laminated glass according to claim 1, wherein the component selected from the phthalocyanine compound, the naphthalocyanine compound, and the anthracocyanine compound contains vanadium atom(s). ### Claim 3 (depends on 1) The interlayer film for laminated glass according to claim 1, wherein the component selected from the phthalocyanine compound, the naphthalocyanine compound, and the anthracocyanine compound is at least one selected from phthalocyanine and phthalocyanine derivative. ### Claim 4 (depends on 1) The interlayer film for laminated glass according to claim 1, wherein the metal oxide particles are tin-doped indium oxide particles or caesium-doped tungsten oxide particles. ### Claim 5 (depends on 4) The interlayer film for laminated glass according to claim 4, wherein the metal oxide particles are tin-doped indium oxide particles. ### Claim 6 (depends on 1) The interlayer film for laminated glass according to claim 1, wherein the thermoplastic resin included in the first heat-shielding layer and the thermoplastic resin included in the second heat-shielding layer each are a polyvinyl acetal resin. ### Claim 7 (depends on 1) The interlayer film for laminated glass according to claim 1, wherein the first heat-shielding layer and the second heat-shielding layer each further contain a plasticizer. ### Claim 8 (depends on 1) The interlayer film for laminated glass according to claim 1, wherein the second heat-shielding layer is laminated on a first surface of the first heat-shielding layer. ### Claim 9 (depends on 8) The interlayer film for laminated glass according to claim 8, wherein one second heat-shielding layer is laminated on the first surface of the first heat-shielding layer, and another second heat-shielding layer is laminated on a second surface of the first heat-shielding layer which is on the opposite side of the first surface. ### Claim 10 (depends on 1) Laminated glass comprising a first member for laminated glass, a second member for laminated glass, and an interlayer film sandwiched between the first member for laminated glass and the second member for laminated glass, wherein the interlayer film is the interlayer film for laminated glass according to claim 1.
