Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a resin composition for non-foamed sheets which is reduced in local elongation of a sheet and is resistant to deformation of an embossed pattern on the sheet surface, in processing, and a non-foamed sheet composed of it.SOLUTION: A non-foamed sheet uses a non-foamed sheet resin composition consisting of a thermoplastic elastomer (A) having specified properties and a modified polypropylene resin (B), and the modified polypropylene resin (B) is obtained by melt kneading of a linear polypropylene resin (a), a conjugated diene compound and (c) a radical polymerization initiator. 【課題】加工する際にシートの局部伸びを低減し、シート表面のシボ模様が変形しにくい非発泡シート用樹脂組成物及びそれからなる非発泡シートを提供する。【解決手段】特定の物性を示す熱可塑性エラストマー（Ａ）と改質ポリプロピレン系樹脂（Ｂ）からなる非発泡シート樹脂組成物を用いた非発泡シート。改質ポリプロピレン系樹脂（Ｂ）が、線状ポリプロピレン系樹脂（ａ）を共役ジエン化合物（ｂ）とラジカル重合開始剤（ｃ）とを溶融混練して得られることを特徴とする非発泡シート用樹脂組成物。【選択図】図１
