This method for producing hydrogel particles comprises: a step for solidifying an aqueous solution, in which a gel agent that forms a non-crosslinked hydrogel is dissolved and which has a gel point of 30 DEG C or more, by bringing the aqueous solution into a liquid phase at a temperature of the gel point or less and a step for crushing a solidification product obtained by solidifying the aqueous solution in which the gel agent is dissolved.本發明之水凝膠粒子之製造方法包括:將溶解有形成非交聯型水凝膠之凝膠劑之凝膠化點為30℃以上之水溶液添加至上述凝膠化點以下之溫度之液相中並使之固化之步驟;及將使溶解有上述凝膠劑之水溶液固化而成之固化物解碎之步驟。
