Washing machine

The present invention provides a washing machine having a structure for preventing entry of water into an ozone production device (42). In the washing machine, an introduction tube (43) is extended downward from the ozone production device (42) and connected to an airflow path member (31). By this, even if there is condensation in the introduction tube (43) by a temperature difference between the inside and outside of the introduction tube (43), water drops caused by the condensation drop downward by gravity toward the airflow path member (31) and do not enter the ozone production device (42). Further, even if water bubbles and detergent bubbles occurring in an outer tub (7) during washing operation enter the introduction tube (43) and turn into water drops when they break, the water drops drop downward by gravity toward the airflow path member (31) and do not enter the ozone production device (42) in the same way as the water drops by the condensation.
