The invention provides an ice maker reliably performing a reliable ice separating operation. The ice maker includes: an evaporator; an ice making plate disposed vertically and making contact with the evaporator at a rear side thereof, the ice maker including a plurality of ice forming parts formed by dividing a front side thereof, surfaces of the ice forming parts being sloped to face downwards; a water tub disposed below the ice making plate to collect water falling from the ice making plate; and an ice bin forming an ice storage space around the water tub to collect ice falling from the ice making plate. Since the ice making plate has a sloped structure, ice may be reliably separated from the ice making plate, and the quality of ice may be improved.
