Abstract
[Problem] The present invention relates to: a heat ray shielding adhesive which is used in bonding to a windowpane and the like and shields heat rays; a heat ray shielding transparent adhesive sheet; and a method for producing the heat ray shielding adhesive. The present invention provides a heat ray shielding transparent adhesive sheet which has high transmittance in the visible light region, low haze and more excellent transparency. [Solution] Transparency and heat ray shielding properties can be imparted in a simpler manner by using a heat ray shielding adhesive composition which contains fine heat ray shielding particles that have a half-value width of the first main peak of from 0.01° to 0.80° (inclusive) as determined by X-ray diffraction pattern, and a heat ray shielding transparent adhesive sheet is therefore able to be produced at low cost.
