Abstract: The present invention relates to a coolant heater comprising: a heating element for heating coolant; a first housing for accommodating the heating element; a cover plate for sealing the first housing in which the heating element is accommodated; a temperature fuse provided in an external space formed by coupling the first housing and the cover plate, and disposed to be adjacent to the cover plate; and a second housing for pressing the temperature fuse so as to pressurize the same toward the cover plate, wherein overheat sensing responsiveness of the heating element is improved such that the overheat of the heating element can be prevented, and failure factors in a part in which the temperature fuse is coupled are reduced such that a durability is improved.
