PROBLEM TO BE SOLVED: To increase the number of insertion and desorption of Li. ! SOLUTION: In this invention, M is an atom or a solid-soluted atom capable of taking a plurality of valences other than a zero valence, and a negative or positive electrode active material has a LixM3P8O29 type crystal structure (provided, x>9). In this invention, a lithium ion battery includes the positive electrode active material. In this invention, M is an atom or a solid-soluted atom capable of taking a plurality of valences other than a zero valence, and a method of manufacturing the negative or positive electrode active material is to manufacture the negative or positive electrode active material having the LixM3P8O29 type crystal structure (provided, x>9) by a soft chemical method or an electrochemical method using a material having a LiyM3P8O29 type crystal structure (y≤9). !
