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 a temperature of the first space and a temperature of the second space and is a vacuum space; a supporting unit configured to maintain the third space; a heat resistance unit configured to reduce heat transfer between the first plate member and the second plate member; an exhaust port through which a gas of the third space is exhausted; a through-part of the first plate member and a through-part of the second plate member for passing a refrigerant pipe (171, 172) therethrough to allow a refrigerant to move between the first space and the second space; and a through sealing part configured to accommodate the refrigerant pipe (171, 172) therein, the through sealing part being configured to seal the pair of through-parts so as to prevent cold air from being conducted between the first space and the second space. characterized in that: the vacuum adiabatic body further comprising a first block supported by the first plate member and a second block supported by the second plate member, so as to be fixed in position and made of a material having thermal conductivity less than that of each of the first plate member and the second plate member, wherein the second block is directly or indirectly coupled to the first block. 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 a temperature of the first space and a temperature of the second space and is a vacuum space; a supporting unit configured to maintain the third space; a heat resistance unit configured to reduce heat transfer between the first plate member and the second plate member; an exhaust port through which a gas of the third space is exhausted; a through-part of the first plate member and a through-part of the second plate member for passing a refrigerant pipe (171, 172) therethrough to allow a refrigerant to move between the first space and the second space; and a through sealing part configured to accommodate the refrigerant pipe (171, 172) therein, the through sealing part being configured to seal the pair of through-parts so as to prevent cold air from being conducted between the first space and the second space. characterized in that: the vacuum adiabatic body further comprising a first block supported by the first plate member and a second block supported by the second plate member, so as to be fixed in position and made of a material having thermal conductivity less than that of each of the first plate member and the second plate member, wherein the second block is directly or indirectly coupled to the first block.
