1. A method for manufacturing a negative electrode material mixture composite for a fluoride ion secondary battery, the method comprising:
a mixing step of mixing a negative electrode active material, a fluoride ion conductive fluoride and carbon black to obtain a negative electrode material mixture; and
a composite particle formation step of subjecting the negative electrode material mixture to grinding and mixing treatment to complex the negative electrode active material, the fluoride ion conductive fluoride and the carbon black so as to obtain composite particles,
wherein the negative electrode active material is aluminum.
