PROBLEM TO BE SOLVED: To provide a hot storage case wherein a temperature difference in the case is small. SOLUTION: Between an external box 11 and an internal box 12, a passage P comprising a pair of right and left vertical passages, and a lateral passage P1 which connects the upper sections of both vertical passages is formed. Then, at approx. the central area in the longitudinal direction of respective vertical passages, a heater 18 (17) which extends in the vertical direction is arranged. Also, a ventilation port 12c1 (12b1) is provided on the upper wall 12a and both of the right and left side walls 12c (12b) of the internal box 12. Then, an air blower, which circulates air in the internal box 12 through the ventilation port provided on the upper wall 12a, the passage P and respective ventilation ports 12c1 (12b1), is provided for this hot storage case. In such a hot storage case, at the upper sections of respective vertical passages, a guide 11f (11e) which guides one section of the circulated air to a heater 18 (17) is provided. At the same time, the ventilation port 12c1 (12b1) provided on both of the right and left side walls 12c (12b) of the internal box 12 is formed into a gate type, and the center in the longitudinal direction of the ventilation port 12c1 (12b1) is made to roughly meet the location where the heater 18 (17) is arranged.
