An aqueous gel ballpoint pen 1 having an ink-storage tube storing an aqueous gel ink containing a pigment as a coloring agent, and a ballpoint pen tip having a ball rotatably held at its leading end and also having an ink flow pore which is formed so that the aqueous gel ink flows from the ink-storage tube to the ball, wherein an ink flow pore diameter r (unit: mm) in the ballpoint pen tip and a storage modulus G' (unit: Pa) at 20.degree. C. of the aqueous gel ink satisfy conditions represented by the following formulas (1) and (2): 0.24.ltoreq.r.ltoreq.0.64 (1), and 1.3.ltoreq.G'.ltoreq.16r-3.2 (2).
