Particularly, since current flows from the first or third terminal 110 or 130 through the heating body 100 to the second terminal 120, the heating unit 100 can be efficiently heated So that the heat exchange efficiency with the cooling water can be improved.

Each of the first to third terminals 110, 120 and 130 may be formed to correspond to the entirety of the protrusion 104 of the heat generating body 100 along the third direction D3.
