Beschreibung
Zusammenfassung:	This reflective film and edge-lit backlight unit using same are characterized by using a resin layer containing polyolefin particles having a viscosity average molecular weight of at least 500,000 at at least one surface of a substrate film. It is possible to provide a reflective film and edge-lit backlight unit that suppress adhesion between the reflective film and a member (for example, a light guide plate) that contacts the reflective film, are at the same time able to suppress damage (scratches and transfer contamination of scraped-off powder) to the contacted member (for example, a light guide plate) and contamination of the contacted member (for example, a light guide plate) resulting from heat, and have favorable heat resistance (low change in color resulting from heat).
