A grommet comprising:
- a tube;
- and
- a flange that has a greater diameter than the tube, the flange having an inner end that is located on an inner side in a radial direction and that is coupled to one end of the tube, wherein:
- the inner end of the flange is formed so as to bulge outward in a radial direction relative to an outer circumferential surface of the tube, and has an outer surface that faces toward the tube and an inner circumferential surface that is located on an opposite side of the outer surface, and faces toward an internal space of the flange, and
- a connection between the one end of the tube and the inner end of the flange is provided with a recess that is recessed in a direction from the outer surface of the inner end to the inner circumferential surface of the inner end,
- wherein the recess has a non-uniform width dimension that gradually decreases from a bulge portion having a largest width of the recess toward the inner end of the flange.
