PROBLEM TO BE SOLVED: To further suppress deterioration of charge / discharge characteristics in a material containing Si. The method for producing porous silicon particles of the present disclosure includes a particle-forming step of melting a silicon alloy containing 50% by mass or more of the first element Al and 50% by mass or less of Si to form particles. , A perforation step of removing the first element in the silicon alloy to obtain porous silicon particles. The porous silicon particles have an average particle size in the range of 0.1 μm or more and 100 μm or less, include skeleton silicon having a three-dimensional network structure having voids, and an average porosity in the range of 50% by mass or more and 95% by volume or less. Yes, the ratio of elements other than oxygen may be such that Si is contained in an amount of 85% by mass or more and Al is contained in a range of 15% by mass or less. [Selection diagram] None
