PROBLEM TO BE SOLVED: To provide an oil-based ink composition for a ball-point pen, capable of surely conducting visual confirmation of a residual amount of the ink, without causing adhesion and stain of the ink to an ink receiving part, even after the composition is stored for a long period or left to be heated. SOLUTION: This oil-based ink composition for the ball-point pen contains one kind of ether polyol, wherein the ether polyol is used as an anti-adhesion agent for the ink, expressed by the general formula, and obtained by addition polymerization of propylene oxide to diglycerol.
