To improve a water cutoff performance.SOLUTION: A grommet 1 comprises: an annular water cutoff part 13 which is inserted to a through hole 101 formed in a mounting panel 100 and cuts off water; and a first partition wall part and a second partition wall part which expand to the inside of the water cutoff part 13 in a radial direction and are disposed so as to close an annular shape of the water cutoff part 13. The water cutoff part 13 includes: a first abutment portion 131 which can be abutted to one side face 101a of a peripheral edge of the through hole 101 in an axial direction X and is annularly formed; a second abutment portion 132 which is provided outside of the first abutment portion 131 in the radial direction, can be abutted to the one side face 101a and is annularly formed; a groove portion 133 which is annularly formed between the first abutment portion 131 and the second abutment portion 132; and a rugged portion 135 which is formed on a peripheral wall inside of the groove portion 133.SELECTED DRAWING: Figure 4
