<div>[[ファイル:Biological cell.svg|thumb|400px|典型的な動物細胞の模式図: (1) [[核小体]](仁)、(2) [[細胞核]]、(3) [[リボソーム]]、(4) [[小胞]]、(5) '''粗面小胞体'''、(6) [[ゴルジ体]]、(7) [[微小管]]、(8) [[滑面小胞体]]、(9) [[ミトコンドリア]]、(10) [[液胞]]、(11) [[細胞質基質]]、(12) [[リソソーム]]、(13) [[中心体]]]]<br />
'''粗面小胞体'''(そめんしょうほうたい、{{lang-en-short|rough-surfaced endoplasmic reticulum, rER}})は、[[リボソーム]]が付着している[[小胞体]]の総称。[[核膜]]の外膜と粗面小胞体は連続している。リボソーム中には[[リボ核酸|RNA]]が多く含まれるため、粗面小胞体は好塩基性に染色される。<br />
<br />
分泌たんぱく質、膜たんぱく質、リソソーム酵素は粗面小胞体膜状の付着リボソームで合成される。[[膵外分泌細胞]]、[[胃底腺]][[主細胞 (胃)|主細胞]]、[[形質細胞]]、[[肥満細胞]]、[[神経細胞]]などの[[蛋白質|タンパク質]]合成が盛んな細胞でよく発達する。分泌された物質はゴルジ体へ輸送される。<br />
