The present invention relates to a method for manufacturing a coil assembly of a fluid heating device for a vehicle, which includes: a coil generating an induced current; a bobbin on which the coil is wound; and a cover surrounding the coil, wherein the bobbin includes a body and a flange disposed at an end of a body. Provided is the method for manufacturing the coil assembly of the fluid heating device for the vehicle, which includes the steps of: a) manufacturing the bobbin by first insert-injecting the flange including a contact increasing part; b) winding the coil on the bobbin; and c) manufacturing the cover by insert-injecting the flange to surround the coil, thereby preventing water from entering between the bobbin and the cover.
