An intermediate film for laminated glass, comprising: a first layer which contains a polyvinyl acetal resin and a plasticizer; and a second layer which is laminated on a first surface of the first layer and which contains a polyvinyl acetal resin and a plasticizer, wherein an absolute value of the difference between SP values of the polyvinyl acetal resin and the plasticizer contained in the first layer is 0.5 or smaller when the SP value is calculated by the Fedors method, and wherein the plasticizer contained in the first layer is a diester compound represented by the following formula: wherein R1 and R2 each represent a C1-C5 organic group; R3 represents an ethylene group, an isopropylene group or an n-propylene group; and p is an integer of 2 to 10, and wherein an amount of the plasticizer is 50 parts by weight or more for each 100 parts by weight of the polyvinyl acetal resin in the first layer, a hydroxy group content in the polyvinyl acetal resin contained in the first layer is lower than a hydroxy group content in the polyvinyl acetal resin contained in the second layer, the difference between the hydroxy group content in the polyvinyl acetal resin contained in the first layer and the hydroxy group content in the polyvinyl acetal resin contained in the second layer is 9.2 mol% or smaller, and the degree of acetylation in the polyvinyl acetal resin contained in the first layer is 8 mol% or lower if the difference between the hydroxy group content in the polyvinyl acetal resin contained in the first layer and the hydroxy group content in the polyvinyl acetal resin contained in the second layer is greater than 8.5 mol% but not greater than 9.2 mol%, a first layer which contains a polyvinyl acetal resin and a plasticizer; and a second layer which is laminated on a first surface of the first layer and which contains a polyvinyl acetal resin and a plasticizer, wherein an absolute value of the difference between SP values of the polyvinyl acetal resin and the plasticizer contained in the first layer is 0.5 or smaller when the SP value is calculated by the Fedors method, and wherein the plasticizer contained in the first layer is a diester compound represented by the following formula: wherein R1 and R2 each represent a C1-C5 organic group; R3 represents an ethylene group, an isopropylene group or an n-propylene group; and p is an integer of 2 to 10, and wherein an amount of the plasticizer is 50 parts by weight or more for each 100 parts by weight of the polyvinyl acetal resin in the first layer, a hydroxy group content in the polyvinyl acetal resin contained in the first layer is lower than a hydroxy group content in the polyvinyl acetal resin contained in the second layer, the difference between the hydroxy group content in the polyvinyl acetal resin contained in the first layer and the hydroxy group content in the polyvinyl acetal resin contained in the second layer is 9.2 mol% or smaller, and the degree of acetylation in the polyvinyl acetal resin contained in the first layer is 8 mol% or lower if the difference between the hydroxy group content in the polyvinyl acetal resin contained in the first layer and the hydroxy group content in the polyvinyl acetal resin contained in the second layer is greater than 8.5 mol% but not greater than 9.2 mol%,
