摘要： A method of manufacturing the positive electrode material for a lithium ion secondary battery includes a first step of mixing Li3PO4, LiOH, H3PO4, an Fe source, a Mn source, and an M source to prepare raw material slurry, and a second step of subjecting the raw material slurry to a reaction under a high temperature and a high pressure. In the first step, mixing amounts of Li and P are set to 3.00≦Li/(Fe+Mn+M)≦3.10 and 1.00≦P/(Fe+Mn+M)≦1.10, mixing amounts of LiOH and H3PO4 are set to 0
