Abstract: A light reflecting body includes a base containing a resin material and a calcium carbonate and includes a metal layer on the surface of the base. The resin material is selected from a polyester resin composition, a polyarylate resin composition, and a mixed resin composition thereof. The calcium carbonate has a BET specific surface area of 1 to 15 m2/g, a pore distribution curve determined by mercury porosimetry that the top of a peak representing interparticle void size is in a pore size range of 0.1 to 1.0 μm, a particle size distribution determined by using an electron microscope that the proportion of particles having a particle size of 0.1 μm or less is 10% or less of the calcium carbonate, and the residue on a sieve having a mesh size of 45 μm after wet sieving of the calcium carbonate is 0.1% or less.
