The positive electrode material contains between 5% by mass or more and 30% by mass or less of a carbon black composite formed by joining together fibrous carbon and carbon black wherein ash is 1.0% or less by mass in accordance with JIS K 1469and the remainder includes olivine-type lithium iron phosphate, and volatile oxygen-containing functional groups which constitutes 1.0% or less by mass of the positive electrode material. The fibrous carbon is preferably a nanotube having a fiber diameter of 5nm or more and 50nm or less and a specific surface area between 50m/g or more and 400m/g or less.",
