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.American Physical Society (APS)Journal Articlehttp://hdl.handle.net/2115/783672470-0010Physical Review D10150550462020-03-31enginfo:doi/10.1103/PhysRevD.101.055046none
