Vacuum adiabatic body and refrigerator

A vacuum adiabatic body comprising:

• a first plate;
• a second plate spaced apart from the first plate to form a vacuum space between the first plate and the second plate;
• and
• a support provided between the first plate and the second plate,
• wherein the support includes:
• a first support plate having a plurality of columns and a plurality of rows arranged, and a plurality of spacer couplers to protrude from the first support plate,
• a second support plate having a plurality of columns and a plurality of rows arranged, and a plurality of spacers to protrude from the second support plate,
• wherein the plurality of spacers of the second support includes a first spacer having a first shape, a second spacer having a second shape, and a third spacer having a third shape, wherein the first shape is different than the second shape and is different than the third shape, and the second shape is different than the third shape, and
• wherein the first spacer has a diameter decreasing toward the first support, and a second and third spacers have a stepped portion.

A vacuum adiabatic body comprising:

• a support disposed in a vacuum space,
• wherein the support includes:
• a first support plate formed to have a grid shape, and a plurality of spacer couplers to protrude from the first support plate,
• a second support plate formed to have a plurality of columns and a plurality of rows arranged to have a grid shape, and a plurality of spacers to protrude from the second support plate, and configured to couple to each of the plurality of spacer couplers to form a plurality of bars;
• and
• wherein the plurality of spacers are arranged in the plurality of columns and the plurality of rows of the second support plate, and
• wherein only spacers having a same shape is provided in a first set of columns of the plurality of columns, and spacers having different shapes are provided in a second set of columns of the plurality of columns.
