PROBLEM TO BE SOLVED: To provide an interior carbon dioxide concentration alarm device for recognizing that a caution state is eliminated, and displaying caution information that does not give uncomfortable feeling to a driver. SOLUTION: A CPU 11 in a combination meter 1 controls an LCD 3 to display caution when the interior CO<SB>2</SB>concentration is the predetermined value or more, and then controls the LCD 3 to display that the CO<SB>2</SB>concentration is lowered and the caution state is eliminated when the interior CO<SB>2</SB>concentration becomes less than the predetermined value, and controls to change the display into CO<SB>2</SB>discharge amount display when the predetermined time or more passes after CO<SB>2</SB>caution or CO<SB>2</SB>decrease is displayed.
