PROBLEM TO BE SOLVED: To facilitate easy visual confirmation of unevenness of coating and presence and absence of coating at the stage of a coating process of an adiabatic layer and to increase the heat insulation property of a container at the same time by forming an adiabatic layer outside of the container and making the outer surface of the adiabatic layer in a rugged form. SOLUTION: On the outer surface of a container 5, an adiabatic layer 10 is formed. The adiabatic layer 10 consists of a material 10a which is structured mainly of resins such as fluororesin, silicone resin, polyether sulfone resin, etc., coated with a coating material on the outer surface of the container 5 in a film thickness to the extent of 40-200μm. The coating material is composed of a mixture of a number of adiabatic particles 10b consisting of inorganic materials with poor heat conductivity such as almina powder, titania powder, aluminum powder, glass powder, glassfiber, mica powder, etc. As for the adiabatic layer 10, based on the adiabatic particles 10b mixed in the base material 10a, the outer surface of the adiabatic layer 10 becomes in a rugged form.
