A laminate for a laminated glass, comprising an interlayer film for a laminated glass laminated with a retardation element interposed between an adhesive layer A and an adhesive layer B, wherein the retardation element contains a liquid-crystal compound and at least one compound selected from the group consisting of a compound represented by the following formula (1), a compound represented by the following formula (2), and a compound represented by the following formula (3). In formula (1), n represents an integer from 3 to 10 and Rrepresents a &#x2014;CH&#x2014;CH&#x2014; group, a &#x2014;CH&#x2014;CH(CH)&#x2014; group, or a &#x2014;CH&#x2014;CH&#x2014;CH&#x2014; group. In formula (2), Rrepresents a &#x2014;(CH)&#x2014; group or a phenylene group and p represents an integer from 4 to 8. In formula (3), Rrepresents a substituted phenylene group. R, R, and Rin formulas (1) to (3) are the same or different, each representing an alkyl group that has a branched structure and that contains at least 5 carbon atoms.
