PROBLEM TO BE SOLVED: To provide a producing device capable of obtaining a lithium composite oxide having more uniform quality in a composition, a grain distribution or the like.SOLUTION: A producing device for a lithium composite oxide includes: a suspension part receiving raw materials to perform slurry adjustment; a wet type pulverization part receiving the slurry having been adjusted in the suspension part and pulverizing the slurry in a wet method to discharge the slurry; an accumulation part accumulating the slurry that has been pulverized and then discharged from the pulverization part; a drying part receiving the slurry from the accumulation part and drying the slurry to form a precursor; and a firing part receiving the precursor and firing the precursor. Piping for feeding the slurry connects from the accumulation part to the drying part. The piping includes a first horizontal part Lextending from the accumulation part in a horizontal direction, a first vertical part Lextending upward in a vertical direction from the end part of the first horizontal part, a second horizontal part Lfurther extending in a horizontal direction from the end part of the first vertical part, and a second vertical part Lfurther extending downward in a vertical direction from the end part of the second horizontal part, and has a total length within 7.0 m.
