PURPOSE: Set thermal insulation boards are provided to integrally have a female connection part, a male connection part, or a female and male connection part to the rim of the thermal insulation boards, to easily interconnect the thermal insulation boards with the same plane while preventing a gap between the thermal insulation boards. CONSTITUTION: One thermal insulation board(10) forms long depressed parts(111) over the longitudinal overall length of the middle part of at least two rim surfaces among four rim surfaces. Another thermal insulation board forms prominent parts(121) over the longitudinal overall length of the middle part of at least two rim surfaces among four rim surfaces. The long depressed part has a shape and size to be fitted to the long prominent part.
