PROBLEM TO BE SOLVED: To provide a hot water supplier capable of improving operability by improving thermal insulation performance, reducing cost of a molded thermal insulating material and improving its strength. SOLUTION: The hot water supplier has a recessed part for a can body in a shape along an outline of a hot water storage can body 1. While invariably keeping the thickness of the recessed part for the can body, equipped with a thermal insulation material (a front part ) 3 having a respectively independent air receiver part which is formed by forming lightening holes for front and back sides alternatively, an air layer is formed by the air receiver part and thermal retention/insulation performance of the hot water storage can body 1 is improved. As a thermal insulation material (an upper part) 7 and a thermal insulation material (a lower part ) 8 are additionally provided at positions where a hot water supply pipe 5 and a water supply pipe 6 are formed, operability is improved.
