Abstract: An ice maker includes an upper tray and a lower tray made of an elastic material. Upper chambers in the upper tray and lower chambers in the lower tray contact each other to define spherical ice chambers, respectively. An ejector-receiving opening is opened to each of the upper chambers. An opening-defining wall extends upward along a circumference of each ejector-receiving opening. An upper ejector passes through the ejector-defining wall and vertically moves to remove ice from the ice chamber, and a driver pivots the lower tray to open and close the upper tray and the lower tray. The upper tray includes a horizontal extension forming a top face of the upper tray, and the upper chamber is positioned below the horizontal extension such that the opening-defining wall is formed at a vertical level equal to or lower than a vertical level of the opening-defining wall.
