Provided are staple fibers for air laid capable of improving dispersibility, and a method for producing the same. The staple fibers for air laid are characterized by including stable fibers to which a fiber treatment agent containing a hydrophilic oil agent and a silicone-containing oil agent is adhered in an amount of 0.7 to 2 wt % of a weight of the staple fibers, wherein a weight ratio of the hydrophilic oil agent and the silicone-containing oil agent contained in the fiber treatment agent (a weight of the hydrophilic oil agent/a weight of the silicone-containing oil agent) is within a range of 60/40 to 90/10, and a moisture content is 2 to 13%.
