PROBLEM TO BE SOLVED: To provide a polyester resin composition maintaining high mechanical strength, dimensional stability and durability which polyester originally has and having largely fine granulated dispersion diameter than conventional techniques and a dispersion phase dispersed in the polyester, a molded body and a polyester sheet having mechanical strength, dimensional stability and durability which polyester originally has and high level light reflection rate, and a polyester sheet having fine holes dispersing uniformly, excellent in reflection property and scattering property of light beams and exhibiting homogeneity in whole area without generating a strength reduction part, a hole or the like in part.SOLUTION: The polyester resin composition contains polyester (A) of 60 to 98 wt.%, 4-methyl-1-pentene polymer (B) of 1 to 25 wt.% and polar group modified styrene elastomer (C) of 1 to 15 wt.%, where the total of (A), (B) and (C) is 100 wt.%. |
