Abstract:	We study the spontaneous CP violation through the stabilization of the modulus tau in modular invariant flavor models. The CP-invariant potential has the minimum only at Re [tau] = 0 or 1/2(mod 1). From this result, we study CP violation in modular invariant flavor models. The physical CP phase is vanishing. The important point for the CP conservation is the T transformation in the modular symmetry. One needs the violation of T symmetry to realize the CP violation.
