The present invention provides an interlayer film for laminated glass which has excellent sound insulating properties even when the thickness is reduced, and also has a low degree of orientation and low shrinkability. The invention relates to an interlayer film for laminated glass which includes at least one layer A containing a thermoplastic elastomer, wherein the thermoplastic elastomer includes a hard segment block and a soft segment block, the layer A has a sea-island phase separated structure in which the hard segment block is included as an island component and the soft segment block is included as a sea component, and the degree of orientation (1) defined by (maximum intensity value&#x2212;minimum intensity value)/(maximum intensity value+minimum intensity value) based on the maximum intensity value and the minimum intensity value in an arbitrary azimuth range of 180&#xb0; including the azimuth at which the intensity reaches the maximum in the azimuthal intensity distribution of periodic scattering or coherent scattering by the hard segment block or the soft segment block obtained for the layer A by small-angle X-ray scattering measurement is 0.9 or less.

An acrylic thermoplastic resin composition is obtained by melt-kneading a methacrylic resin (A) and a polyvinyl acetal resin (B) at a resin temperature of not less than 140&#xb0; C. while applying shear at a shear rate of 100 secor more, and then cooling the kneaded product to not more than 120&#xb0; C. In the acrylic thermoplastic resin composition, at least the methacrylic resin (A) forms a continuous phase, and among glass transition temperatures of the acrylic thermoplastic resin composition, a glass transition temperature Tgascribed to the methacrylic resin (A) indicates a value between a glass transition temperature (Tg) of the methacrylic resin (A) alone and a glass transition temperature (Tg) of the polyvinyl acetal resin (B) alone. A film- or sheet-like molded article is obtained by molding the resin composition. An acrylic resin composite is obtained by laying a layer of metal and/or metal oxide on at least one side of the acrylic resin molded article.
