Disclosed are an insulation structure of a liquefied gas cargo hold and a manufacturing method thereof, which can enhance insulation performance. The insulation structure of a liquefied gas cargo hold according to an embodiment of the present disclosure comprises: a plurality of secondary insulation panels which are installed on an inner wall of a ship body, and are disposed to be spaced apart from each other; a first flat joint which is inserted to come in contact into the inner wall of the ship body in a spacing unit formed between two secondary insulation panels disposed adjacent to each other; and a second flat joint which is inserted to come in contact with the first flat joint in the spacing unit. A secondary barrier is disposed at an upper side of the secondary insulation panel. The secondary barrier includes a corrugated portion protruding toward the inner wall of the ship body in the direction of the spacing unit to be accommodated in the spacing unit. The second flat joint may be in contact with the corrugated portion, and a surface in contact with the corrugated portion may be deformed to be closely in contact with the corrugated portion when coming in contact with the corrugated portion.
