Embodiments of the present invention provide a conical inductor, a printed circuit board, and an optical module, and relate to the field of communications technologies. By changing a pin of the conical inductor, accuracy of alignment between the pin of the conical inductor and a pad of the printed circuit board is improved, and pseudo soldering of the conical inductor is also reduced. The conical inductor provided in the embodiments of the present invention includes: a housing, a conical coil located inside the housing, and two pins respectively connected to two ends of the conical coil, where one end of the first pin is connected to one end of the conical coil, the other end of the first pin is connected to a hole in the first side wall in a fastened manner, one end of the second pin is connected to the other end of the conical inductor, and the other end of the second pin is connected to a hole in the second side wall in a fastened manner; and each of the first pin and the second pin includes one segment of waveform segment fluctuating in a direction perpendicular to the top wall, where each trough of the waveform segment is connected to the printed circuit board in a fastened manner. |
