The present invention provides a coil assembly of a fluid heating apparatus for a vehicle. The coil assembly includes: a coil generating induced current; a bobbin on which the coil is wound; and a cover surrounding the coil, wherein the bobbin has a body and a flange disposed at an end of the body, and a flange includes a contact area increasing portion. According to the present invention, at least a portion of the body and at least a portion of the cover come in contact with the contact area increasing portion to seal the coil. According to the present invention, it is possible to prevent water from flowing between the bobbin and the cover.
