PROBLEM TO BE SOLVED: To provide a pump for restraining the occurrence of water leakage in a joining part since the casing joining part is vacuum-deposited. SOLUTION: An impeller 1 is rotatably journaled to a motor 2, and is loaded in a first casing 3. The first casing 3 is provided with a water suction port 4 taking in water and hot water and a water discharge port 5 discharging the water and the hot water, and the motor 2 is threadedly engaged with a second casing 6. Rubber packing (unillustrated) is fixed to a contact plane 7 of the first casing and the second casing. When applying vacuum deposition to a pump casing 8 constituted as above-mentioned, since aluminum powder used for deposition coats the whole casing, the contact plane is also coated, and the waterproof effect insufficient only by the rubber packing can be compensated.
