PROBLEM TO BE SOLVED: To provide a lenticular lens sheet and a transmission type screen which hardly cause the partial lowering of contrast and the lowering of luminance, and also hardly cause irregular gradation. SOLUTION: In the lenticular lens sheet 10 having a stripe light absorption part 12 and a stripe light transmission part 13 positioned between the light absorption parts 12 and 12, the line-width W of the light absorption part 12 is formed so that the triplication (3σ) of the standard deviation of the line-width may be≥5% and≤15% of the average of the linewidth.
