PURPOSE: An electric boiler integrated with a header is provided to extend the service life of the heater, and to prevent corrosion in the heater as a ceramic heater is inserted into a mounting hole. CONSTITUTION: An electric boiler integrated with a header comprises a water collecting cylinder(3), a plurality of distribution holes, heating chambers, mounting holes, a ceramic heater(23), first and second caps. The water collecting cylinder supplies water to heating pipes or collects the water from the heating pipes. The distribution holes are linked to the water collecting cylinder from one side of a metal block, and connect the water collecting cylinder to an outer heating pipe. The heating chambers are formed side by side with the water collecting cylinder. The mounting holes are placed between the water collecting cylinder and the heating chambers, and formed in a longitudinal direction of the metal block. The ceramic heater is closely inserted into the mounting holes without a clearance. The first and second caps are formed on one and the other ends of the metal block, respectively. The connecting pipes of the first and second caps connect the water collecting cylinders or heating chambers each other.
