To provide a method of mounting a stud bolt capable of reducing the weight of a mounting plate and securing the mounting strength of the stud bolt.

In the method of mounting the stud bolt provided in a standing manner on the metal mounting plate, an insertion hole 11b formed at the mounting plate 11 for the stud bolt 20 has a rising portion 11c formed of a peripheral edge projected from one side of the mounting plate 11 by burring, and the stud blot 20 has a seat 22 for abutting on the other side of the mounting plate 11 and a plastic deformation portion 23 projecting from the insertion hole 11b in the same direction with the rising portion 11c. The method includes a step for plastically deforming the plastic deformation portion 23 and the rising portion 11c by caulking to hold the rising portion 11c which is bent to the outside of the insertion hole 11b and lapped at the one side of the mounting plate 11 between the plastic deformation portion 23 and the seat 22.
