Heating element having fuse function and heater unit comprising same

A heating element having a fuse function, and configured to heat a fluid, the heating element comprising:

• a plurality of heat sources which generate heat to heat the fluid when power is applied;
• a fuse member having two end portions, wherein each of the two end portions is physically connected to one of two heat sources disposed to be spaced apart from each other by a gap, wherein the fuse member connects the two heat sources in series, and wherein the fuse member is fused to cut an electrical connection of the two heat sources when a temperature is higher than or equal to a preset temperature;
• and
• an insulating member which surrounds the plurality of heat sources and the fuse member,
• wherein each of the plurality of heat sources is a plate-shaped conductive member having a predetermined area, and
• wherein the fuse member is disposed between the two heat sources which are disposed to be spaced apart from each other by the gap in a longitudinal direction of the heating element.
