PROBLEM TO BE SOLVED: To make uniform heating to an article to be cooked by improving temperature distribution. SOLUTION: There are provided a heating chamber 7 for accommodating an article 12 to be cooked and heating and cooking the article, an all primary air type burner 13, a grill 9 for placing the article 12 on a lower stage from the burner 13, and an exhaust guide section 2 protruded into the heating chamber 7 in a substantially V shaped cross section at a ceiling surface center of the heating chamber 7 in a grill. An upper portion of the heating chamber 7 in the grill is filled with combustion exhaust gas, which gas is in turn overflowed from a vent hole 16 communicated with an exhaust chamber 17 to heat the article 12 with convection heat due to the combustion exhaust gas. As a result, the combustion exhaust gas injecting from left and right burners 13 is guided downward along a V shaped slope while filling the upper portion of the heating chamber 7 with the combustion exhaust gas, whereby heating to the article 12 is made uniform.
