PROBLEM TO BE SOLVED: To provide a manufacturing method of rotational speed sensor in which manufacturing cost can be reduced, while preventing breakage of winding. SOLUTION: Opposite end parts of a winding W constituting a sensor part 3 wound around a bobbin 31 are bonded to independent interconnecting terminals 5, 6 secured to the terminal fixing part of the bobbin 31, and after the end art of a cable for outputting sensor signal is bonded to the interconnecting terminal 5, 6, a casing is formed on the outer circumference of the bobbin 31 by resin molding thus manufacturing a rotational speed sensor 1. In such a manufacturing method of rotational speed sensor, the end part of the winding W on the interconnecting terminal side is covered with a solid member 7 for blocking intrusion of resin injected at the time of resin molding, and the bobbin 31 is resin molded under covered state.
