A dishwasher is provided which can reduce the discharge of noise produced by the dishwasher, thereby preventing a user from being upset due to the noise and achieving not only a comfortable use environment but also an improvement in productivity. With the dishwasher, it is possible to prevent the noise, caused during operation of the dishwasher, from being discharged from a lower side of a door, by use of a sound-insulation member with a simplified configuration. In the manufacture of the dishwasher, improved assembly productivity can be accomplished.
