The present invention relates to a hot water generation apparatus and a water purifier comprising same and, more particularly, to a hot water generation apparatus and a water purifier comprising same, in which a collection space inside a case member is disposed above a receiving space in which raw water is accommodated, and has an inclination surface having a predetermined angle of inclination, and a steam outlet through which steam can be discharged is disposed above the collection space, separately from a hot water outlet, so that steam is removed in advance through the steam outlet along the inclination surface before hot water is discharged to the outside. Therefore, since hot water free of steam is discharged and a regular flow of hot water is formed in a straight line along the direction of gravity, user safety is enhanced, aesthetics are improved, and the best user experience can be provided.
