A vacuum adiabatic body comprising: a first plate member configured to define at least a portion of a wall for a first space; a second plate member configured to define at least a portion of a wall for a second space having a temperature different from that of the first space; a sealing part configured to seal the first plate member and the second plate member so as to provide a third space that has a temperature between the temperature of the first space and the temperature of the second space and is a vacuum space; a supporting unit configured to maintain the third space and including a bar configured to maintain a gap between the first plate member and the second plate member; a heat resistance unit configured to reduce a heat transfer amount between the first plate member and the second plate member; an exhaust port configured to discharge a gas within the third space; and a pipeline placed in the third space, wherein movement of the pipeline in a horizontal direction is restricted by the supporting unit; and at least one spacing member (100, 200) interposed between the pipeline and the supporting unit, wherein the spacing member (100, 200) is made of a non-metallic material and comprises a supporting part (110, 210) configured to accommodate the pipeline so as to restrict the movement of the pipeline; characterized in that: - the spacing member (100, 200) comprises at least one wing (120, 121, 220, 221) extending from the supporting part so as to be hung and supported by the bar; and - at least one supporting protrusion (140, 240) extending to at least one plate member of the first plate member or the second plate member is disposed on at least one of the wing (120, 121, 220, 221) or the supporting part (110, 210). a first plate member configured to define at least a portion of a wall for a first space; a second plate member configured to define at least a portion of a wall for a second space having a temperature different from that of the first space; a sealing part configured to seal the first plate member and the second plate member so as to provide a third space that has a temperature between the temperature of the first space and the temperature of the second space and is a vacuum space; a supporting unit configured to maintain the third space and including a bar configured to maintain a gap between the first plate member and the second plate member; a heat resistance unit configured to reduce a heat transfer amount between the first plate member and the second plate member; an exhaust port configured to discharge a gas within the third space; and a pipeline placed in the third space, wherein movement of the pipeline in a horizontal direction is restricted by the supporting unit; and at least one spacing member (100, 200) interposed between the pipeline and the supporting unit, wherein the spacing member (100, 200) is made of a non-metallic material and comprises a supporting part (110, 210) configured to accommodate the pipeline so as to restrict the movement of the pipeline; - the spacing member (100, 200) comprises at least one wing (120, 121, 220, 221) extending from the supporting part so as to be hung and supported by the bar; and - at least one supporting protrusion (140, 240) extending to at least one plate member of the first plate member or the second plate member is disposed on at least one of the wing (120, 121, 220, 221) or the supporting part (110, 210).
