Abstract:
There is provided an interlayer film for a laminated glass having improved appearance which has a MD and TD direction; and one end, and another end being opposite side of and thicker than the one end. The one end and other end are positioned on both sides of the interlayer film in the TD direction. When the distance between the one end and other end is X, the absolute value for the difference between the largest and smallest thermal shrinkage ratios from among three thermal shrinkage ratios is 15% or less. The three thermal shrinkage ratios are positioned from the one end towards the other end in MD direction with a first thermal shrinkage ratio at 150° C. at a first position at 0.05X, a second thermal shrinkage ratio at 150° C. at a second position at 0.5X, and a third thermal shrinkage ratio at 150° C. at a third position at 0.95X.
