  "textContent": "This positive electrode active substance for a non-aqueous electrolyte secondary battery contains: a lithium-containing transition metal oxide having secondary particles formed by aggregation of primary particles; and at least a tungsten compound and a boron compound that are present between primary particles. The present invention is characterized in that: the amount of tungsten element eluted when the positive electrode active substance is washed for 5 minutes with a 0.01 mol/L aqueous solution of sodium hydroxide is 60% or less of the amount of tungsten element detected when the positive electrode active substance is dissolved in a mixed acid containing hydrofluoric acid, nitric acid and hydrochloric acid; and the amount of boron element eluted when the positive electrode active substance is washed for 1 minute with ion exchanged water is 80% or more of the amount of boron element detected when the positive electrode active substance is dissolved in hydrochloric acid.",
