Zusammenfassung:	To provide a technique capable of efficiently obtaining a positive electrode for a battery having excellent releasability from a mold and a nonaqueous secondary battery including the positive electrode.SOLUTION: A positive electrode for a coin-type nonaqueous electrolyte secondary battery according to the present invention includes: a granular mixture which comprises a positive electrode active material comprising a transition metal composite oxide, a conductive aid, and a binder comprising PTFE; and a lubricant containing hydrophobic silica. The positive electrode is characterized to be compression-molded into a pellet shape.SELECTED DRAWING: Figure 1 【課題】本発明は、金型からの離型性に優れた電池用正極と該正極を備えた非水電解質二次電池を効率よく得ることができる技術の提供を目的とする。【解決手段】本発明に係るコイン形非水電解質二次電池用正極は、遷移金属複合酸化物からなる正極活物質と、導電助剤と、ＰＴＦＥからなる結着剤とを含んでなる顆粒状の合剤と疎水性シリカを含有する滑剤とを含み、ペレット形状に圧縮成型されてなる。【選択図】図１
