Ice maker

An ice maker comprising:

• a refrigerant pipe having a pipe passage formed therein for a refrigerant to flow;
• a finger protruding from the refrigerant pipe and having a finger space communicating with the pipe passage for the refrigerant to flow;
• a heater including a heating part provided in the refrigerant pipe to heat the finger, and an extension part extending from one end of the heating part to an outside of the refrigerant pipe;
• a heater holder surrounding at least a portion of the extension part;
• and
• a sealing element that prevents moisture from entering through a gap between an outer peripheral surface of the extension part and an inner peripheral surface of the heater holder,
• wherein the heater holder includes:
• an inner holder part further surrounding an outer peripheral surface of the heating part;
• and
• an outer holder part surrounding at least a portion of the outer peripheral surface of the extension part, and
• wherein the sealing element is a tube having elasticity, and surrounds the outer holder part while being in close contact with the outer holder part on one side, and surrounds the extension part while being in close contact with the extension part on the other side.
