Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ink composition for a ballpoint pen, which highly strikes a balance between a direct flow-preventing function and a temporal stability without degrading writing performance.SOLUTION: This ink composition for a ballpoint pen contains at least a crystalline cellulose and resin particles. It is preferable that: the mass ratio of the resin particles to the crystalline cellulose is 1 to 6; and the average particle diameter of each of the resin particles is 0.3 to 1.0 μm.
