Beschreibung
Zusammenfassung:	The present invention addresses the problem of providing a white-reflecting film that resists deflecting under heat while having exceptional reflection characteristics. The problem is overcome by a white-reflecting film that has a reflective layer A, wherein the white-reflecting film satisfies either condition (a) or condition (b) that the reflective layer A (a) comprises a thermoplastic resin composition A1 containing calcium carbonate particles in a thermoplastic resin A, the content of the calcium carbonate particles being 10─70% by mass with respect to the mass of the thermoplastic resin composition A1, or (b) comprises a thermoplastic resin composition A2 containing calcium carbonate particles in the thermoplastic resin A, and a resin that is incompatible with the thermoplastic resin A, the content of the calcium carbonate particles being 5─69% by mass with respect to the mass of the thermoplastic resin composition A2, the content of the incompatible resin being 1─40% by mass with respect to the mass of
