Provided is a PSA sheet having limited light transmission with reduced PSA-entering light. A PSA sheet having a PSA layer is provided. The PSA layer comprising at least two species of colorants. The PSA layer has a light transmittance of 30% or lower and a light reflectance of 8% or higher.

Pressure-sensitive adhesive sheet

The invention provides a PSA sheet having a PSA layer exhibiting superior light shielding. Provided is a PSA sheet comprising a PSA layer that includes a PSA polymer. Carbon black particles are dispersed in the PSA layer. The average particle size of the carbon black particles dispersed in the PSA layer is 300 nm or smaller. The average particle size is an average particle size determined on the basis of a number-based particle size distribution by TEM observation.
