Abstract
An ice tray includes a tray section and a heater. The tray section has a first face and a second face opposite to the first face. The first face temporarily retains water and the water is cooled to make ice. The heater is unitarily molded with the tray section at the second face, and warms the tray section for the ice to come off the tray section.
