PURPOSE: A tube plate for an evaporator is provided to allow flux to evenly infiltrate into a coupling surface and an inside of the coupling surface of the tube plate of a laminated type evaporator for an automobile even through wet flux applying method during flux applying process necessary to manufacture the tube plate. CONSTITUTION: A plurality of bumps(100) are mounted in channels of an upper plate(23) and a lower plate(25) forming a tube plate body(20) to increase turbulence of refrigerant and reinforce rigidity of the tube plate, and comprises an oval body, coupling surfaces(110) formed on both ends of the body as flanges; and grooves(120) concavely formed on centers of the coupling surfaces. The bumps placed on one side of a diaphragm(14) have fine holes(130) penetrating centers of the grooves to allow flux to easily infiltrate into the coupling surfaces by capillary phenomenon even when flux is applied through wet flux applying method.
