PROBLEM TO BE SOLVED: To provide a night board having high heat insulating performance, and free from dew condensation and frost formation on an outer surface. SOLUTION: This night board for closing a front opening of a refrigerating-freezing warehouse for picking, opened at its front face is composed of a heat insulating board 81 for blocking intrusion of heat from the external, and a plurality of heat insulating panels 80 surrounded by an upper frame mounted on an upper edge section of the heat insulating board 81, a lower frame mounted on a lower edge section, a left frame 85 mounted on a left side edge section, and a right frame 86 mounted on a right side edge section, thus the night board of high heat insulating performance can be provided, and the dew condensation and frost formation on the outer surface of the night board can be prevented.
