PROBLEM TO BE SOLVED: To provide a collectable white reflection film capable of sufficiently suppressing scratches of a light guide plate and obtaining a film having excellent film forming properties even when the film is manufactured using a collected film as a self-collected raw material.SOLUTION: The white reflection film has a reflective layer A and a support layer B consisting of a thermoplastic resin composition including agglomerated particles in a thermoplastic resin. The agglomerated particles have a primary particle size (dp) of 3 μm or less and a secondary particle size (ds) of 10 μm or less, and the content thereof in the support layer B is 1 volume% or more and 50 volume% or less on the basis of the volume of the support layer B. The support layer B forms at least one outermost layer of the white reflection film, and a ten point average roughness (Rz) in the surface of the support layer B forming the outermost layer on the side opposite to the reflective layer A satisfies a relation of 0.1×ds(μm)≤Rz(μm)≤0.7×ds(μm). |
