PROBLEM TO BE SOLVED: To provide an intermediate film for laminated glass and laminated glass using the intermediated film which are excellent in transparency, a heat shielding property, and electromagnetic wave transmittance. SOLUTION: The intermediate film is composed of a polyvinylbutyral resin, plasticizer, and a tin doped indium oxide(ITO) particle and/or an antimony doped indium oxide(ATO) particle of 0.1-3 wt.pt., the mean particle diameter of a tin doped indium oxide(ITO) particle or an antimony doped indium oxide(ATO) particle is <=80 nm, and dispersed such that the numbers of particles having >=100 nm particle diameter are <=1/μm<2> . The laminated glass using the film has the electromagnetic wave shielding property for 1-10 MHz or 2-26.5 GHz is <=10 dB.
