Disclosed is a fine bubble water generator including: a housing being configured with an inflow line on one end thereof where air and fluid enters and a discharge line on an opposite end where fine bubble water is discharged; a partition allowing the air and fluid entered into the inflow line to flow in zigzags inside the housing; and a fine bubble water generation cylinder unit, being inserted into a space formed by the partition, allowing the air and fluid to be induced to collide with a surface thereof having bumps formed thereon and on an inner circumferential surface of the housing or the partition, thereby refining air bubbles and fluid by frictional force caused by a flat surface and the partition.
