A dish washer with an improved flow channel of air passing through an adsorbent includes a tub to wash dishes, a drying device to supply air into the tub to dry the dishes, and an adsorbent case provided in the drying device. The adsorbent case includes an inner space in which an adsorbent to adsorb moisture contained in air in the tub is provided, and at least one mesh unit located in the inner space to form a flow channel of air passing through the adsorbent. The flow channel is formed in the adsorbent using the mesh unit to reduce flow resistance of air flowing through the adsorbent. Air rapidly passes through the flow channel, thereby reducing drying time.
