PURPOSE: To make it possible to pour water, etc., in a water-containing tray even under a condition wherein a grill door is closed by providing an opening from which the grill water-containing tray can be pulled out forward even under a condition wherein the grill door is closed, at a lower part of the grill door.

CONSTITUTION: A grill opening 31 which is formed at an approx. central part of a front surface plate 26 being attached to the front surface side of a gas stove main body 25 is opened/closed by a grill door 32. On the bottom part of the grill opening 31, a grill water-containing tray 34, on which a grill 33 is mounted, is stored removably to this side. For such a grill structure, the grill door 32 is formed in such a manner that the front surface may become an approx. gate-form, and a door glass 44 is provided on a flat plate part 43 of the grill door 32. At the same time, an opening 36 is provided at a lower part of the grill door 32. Then, through the opening 36, the grill water-containing tray 34 is made removable by being pulled out even under a condition wherein the grill door 32 is closed. By this method, the heat in the grill can be prevented from scattering, and the heat efficiency can be improved.
