Zusammenfassung:	PROBLEM TO BE SOLVED: To provide: cured phenol resin particles having a large surface area; a method for advantageously producing the same; and a method for advantageously producing useful activated carbon particles by using the cured phenol resin particles. SOLUTION: When the cured phenol resin particles are produced by reacting phenols and aldehydes in the presence of an alkylbenzene sulfonic acid and a protective colloid to obtain heat-curable phenol resin particles and then, curing the heat-curable phenol resin particles, the aldehydes are used in a ratio of ≥1.1 mol to 1 mol of the phenols, Arabian gum derived from trees of the Acacia senegal species is used as the protective colloid, and the use amount of the Arabian gum is adjusted to be ≥0.001 and
