[Solution] In the present invention, in an inter-structure insulation and moisture-proof structure (1,1') that provides insulation and moisture-proofing to the inside of the structure (2,3) by providing insulation and moisture-proofing material between the divided structure (2,3), a pair of insulation bodies (7,8) are provided detachably between the divided structure (2,3) and a flexible moisture-proof body (6,9) is provided in a flexed state to cover the outside of the detachable portion of the pair of insulation bodies (7,8). Furthermore, the moisture-proof body (6,9) is provided in a double layer on the outside of the detachable portion of the pair of insulation bodies (7,8). In addition, the ends of the moisture-proof body (6,9) are sandwiched between the structure (2,3) and the insulation body (7,8).
