PURPOSE: A method for fixing a core of a proximity switch is provided to prevent error of detection of proximity switch, while achieving improved workability by attaching the core surface of the printed circuit board through the use of epoxy resin. CONSTITUTION: A method comprises the first step(SS1) of positioning a magnet of a predetermined size onto a table; the second step(SS2) of mounting a case onto the magnet; the third step(SS3) of injecting an epoxy resin into the case in such a manner that the magnet and the case are integrated into a single body; the fourth step(SS4) of injecting a printed circuit board into the case; and the fifth step(SS5) of permitting the core of the printed circuit board to press-contact the sensing portion of the case, and fixing the cable and the cap.
