Disclosed is a reflective sheet which contains a resin composition including not less than 50 volume% and less than 80 volume% of a polypropylene resin (A) and not less than 20 volume% and less than 50 volume% of a resin (B) which causes phase separation from the polypropylene resin at a temperature at which the polypropylene resin can be stretched, and has a pore inside. The reflective sheet is characterized in that, in a cross section of the reflective sheet in the thickness direction, the standard deviation of the ratio (X/Z) between the length (X) in the plane direction and the length (Z) in the thickness direction of the resin (B) phase is not less than 0.2. |
