굽힘 특성 및 표면 평활성이 우수한 방향족 폴리카보네이트 수지 시트·필름을 제공한다. 강화 충전재를 배합한 폴리카보네이트 수지 시트·필름의 시트 압출 제조 조건의 조정에 의해, 종래에는 없는 표면 평활성이 우수한 시트를 얻을 수 있다는 것을 발견했다. 또한 그 시트를 압공 성형, 열프레스 성형에 이용하는 것에 의해, 우수한 외관의 열부형품이 얻어진다는 것을 발견했다. Provided is an aromatic polycarbonate resin sheet/film which has excellent bending characteristics and surface smoothness. It is found that a sheet having excellent surface smoothness, which cannot be achieved by conventional sheets, can be obtained by adjusting sheet extrusion conditions for a polycarbonate resin sheet/film into which a reinforcing filler is blended. It is also found that a thermally shaped article having excellent appearance can be obtained by using this sheet in pressure molding or in thermal press molding.
