A radius of a dense star on the colour superconducting phase is investigated in an extended NJL type model with two flavours of quarks. Since the model is non-renormalizable, the results depend on the regularization procedure. Here, we apply the dimensional regularization and evaluate the radius of a dense star. Evaluating the TOV equation, we show the relationship between the mass and radius of the dense star in the dimensional regularization.
