An LED lighting sheet () for animal/plant growth includes an array of LED chips (). At any location 50 mm away from the LED chips () in a lower region below the LED lighting sheet () for animal/plant growth, a photosynthetic photon flux density converted by input power and normalized by an average value over the lower region is greater than or equal to 0.2. A variation in photosynthetic photon flux densities respectively measured at locations 50 mm away from the LED chips () in the lower region below the LED lighting sheet () for animal/plant growth is less than or equal to 0.5 in standard deviation when normalized by the average value.

The present invention provides a volume hologram transfer foil which has good foil cutting characteristics and is used to manufacture a volume hologram laminate by transferring a volume hologram layer to an adherend by thermocompression. The volume hologram transfer foil includes a base material, a protective layer, a volume hologram layer, and a heat seal layer, wherein the protective layer contains a hard coat component, a rupture elongation control component, and a foil cutting characteristic control component which has a thermal expansion coefficient different from those of the hard coat component and rupture elongation control component and is incompatible with the two components.
