PURPOSE: Provided are reflectors constituted by laminating silver on polymer films and lamp reflectors using the reflectors and, more particularly, a reflector having a multi-layer structure primarily constituted by silver which is excellent in light resistance and wet heat durability, and a lamp reflector using the reflector. CONSTITUTION: A lamp reflector includes at least a substrate(A) and a reflective layer(100) formed on the substrate(A), the reflective layer(100) including an underlying layer(B), a metal layer(C) made primarily of silver and a protective layer(D) comprising an inorganic substance, the lamp reflector having a total reflectance of 90% or more at a wavelength of 550 nm after being irradiated from a side of the reflective layer by a simulated solar radiation having an irradiation intensity of 500 mW/cm at 100 Deg.C for 300 hours.
