There is provided an interlayer film for laminated glass enabling laminated glass in which a poor appearance is suppressed to be obtained because wrinkles are hardly generated in the interlayer film. The interlayer film for laminated glass according to the present invention has an MD direction and a TD direction and has one end and the other end being at the opposite side of the one end and having a thickness thicker than the one end, the one end and the other end are respectively positioned at both sides in the TD direction of the interlayer film, and when a distance between the one end and the other end is defined as X, the absolute value of a difference between the largest thermal shrinkage ratio among three thermal shrinkage ratios of the first thermal shrinkage ratio at 150°C in the MD direction on a first position apart from the one end by 0.05X toward the other end, the second thermal shrinkage ratio at 150°C in the MD direction on a second position apart from the one end by 0.5X toward the other end, and the third thermal shrinkage ratio at 150°C in the MD direction on a third position apart from the one end by 0.95X toward the other end and the smallest thermal shrinkage ratio among the three thermal shrinkage ratios is 5% or less.
