To provide a metallocene compound that has excellent solvent solubility and also has a sufficient capability as a catalyst component, a catalyst for olefinic polymerization containing the same, a method for producing the catalyst, and a method for producing an olefinic polymer.SOLUTION: The present invention provides a metallocene compound represented by a specific formula, having a chemical structure with a specific substituent introduced to a xylene skeleton constituting a crosslinked part of the metallocene compound comprising an orthoxylenebisindenyl complex. A catalyst for olefinic polymerization is produced by bringing the metallocene compound (component (A)) into contact with a compound (component (B)) that reacts with the component (A) to form a cationic metallocene compound, with a particulate carrier (component (C)), and further optionally with an organic aluminum compound (component (D)).SELECTED DRAWING: None 【課題】溶剤溶解性に優れ、且つ、触媒成分として充分な能力も保有しているメタロセン化合物、それを含むオレフィン重合用触媒、当該触媒の製造方法、及び、オレフィン重合体の製造方法を提供する。【解決手段】特定の式で表されるメタロセン化合物であり、オルトキシレンビスインデニル錯体からなるメタロセン化合物の架橋部を構成しているキシレン骨格上に特定の置換基が導入された化学構造を有する。前記メタロセン化合物（成分（Ａ））を、当該成分（Ａ）と反応してカチオン性メタロセン化合物を生成させる化合物（成分（Ｂ））、微粒子担体（成分（Ｃ））、さらに必要に応じ有機アルミニウム化合物（成分（Ｄ））と接触させることにより、オレフィン重合用触媒を製造する。【選択図】なし
