PROBLEM TO BE SOLVED: To provide a positive electrode slurry, a power storage device positive electrode, a method for manufacturing a power storage device positive electrode, a power storage device, and a method for manufacturing a power storage device which enable the exhibition of superior charge and discharge characteristics.SOLUTION: A positive electrode slurry comprises: (A) a polymer; (B) an olivine type lithium-containing phosphate compound; and (C) a liquid medium. The polymer (A) includes a diene based polymer having a repeating unit Mc originating from an unsaturated carboxylic acid, a repeating unit Md originating from a conjugated diene compound, and a repeating unit Me originating from aromatic vinyl. Supposing that the content of the olivine type lithium-containing phosphate compound (B) is 100 pts.mass, the content of the polymer (A) is within a range of 0.5-1.5 pts.mass.SELECTED DRAWING: None 【課題】優れた充放電特性を発現可能な正極用スラリー、蓄電デバイス正極、蓄電デバイス正極の製造方法、蓄電デバイス、及び蓄電デバイスの製造方法を提供すること。【解決手段】（Ａ）重合体と、（Ｂ）オリビン型リチウム含有リン酸化合物と、（Ｃ）液状媒体と、を含有し、前記（Ａ）重合体が、不飽和カルボン酸に由来する繰り返し単位Ｍｃと、共役ジエン化合物に由来する繰り返し単位Ｍｄと、芳香族ビニルに由来する繰り返し単位Ｍｅと、を有するジエン系重合体を含有し、前記（Ｂ）オリビン型リチウム含有リン酸化合物の含有量１００質量部に対して、前記（Ａ）重合体の含有量が０．５〜１．５質量部の範囲にあることを特徴とする正極用スラリー。【選択図】なし
