1. A grommet that is mountable into a mounting hole of a vehicle body panel through which a wire harness is passable, the grommet comprising:
an opposing portion that opposes a portion surrounding the mounting hole in the vehicle body panel in a mounting state in which the grommet is mounted into the mounting hole of the vehicle body panel; and
a water-blocking portion in an annular shape that extends from the opposing portion,
wherein the water-blocking portion contacts the vehicle body panel and surrounds the mounting hole in the mounting state,
the water-blocking portion includes:
a base portion that extends from the opposing portion toward the vehicle body panel;
a first lip portion that extends from a leading end of the base portion toward the vehicle body panel while inclining toward an outer circumference of the grommet; and
a second lip portion that extends from the leading end of the base portion toward the vehicle body panel while inclining toward an inner circumference of the grommet,
a height, with respect to the opposing portion, of the first lip portion is different from a height, with respect to the opposing portion, of the second lip portion in an unmounted state in which the grommet is unmounted from the vehicle body panel, and
