A coil structure for generating a uniform magnetic field and a coil apparatus having the same are disclosed. The coil apparatus has a plurality of coil units, and each of the coil units includes a sub-coil and a plurality of wire sections. The sub-coil has an eccentric-coil portion and two circuit connecting portions. The two circuit connecting portions are respectively connected to two segments of the eccentric-coil portion. The wire sections are arranged in parallel at intervals, are opposite the sub-coil, overlap the sub-coil, and are relatively inclined to the sub-coil. The circuit connecting portions of the segments of the coil units are connected to each other to form an auxiliary coil. A center position of the sub-coils is corresponding to a center position of the auxiliary coil so that a current flows through the sub-coils and the auxiliary coil to generate a uniform magnetic field.
