The present invention relates to a membrane-type liquefied gas storage tank and a vessel comprising the same. In accordance with the present invention, the liquefied gas storage tank comprises: a first wall made of metal membrane sheets having a first corrugated unit, and coming in contact with liquefied gas inside; a second wall made of metal membrane sheets having a second corrugated unit, and installed on a first insulation wall; the first insulation wall made of a combination of a plurality of first insulation panels, which are made by laminating a first upper plywood, a first insulator, and a first lower plywood, and installed between the first wall and the second wall; a second insulation wall made of a combination of a plurality of second insulation panels, which are made by laminating a second upper plywood, a second insulator, and a second lower plywood, and installed between the second wall and a hull; and a fastening apparatus which simultaneously fastens and fixes the hull, the second insulation wall, the second wall, and the first insulation wall. The fastening apparatus includes: a tension spring placed in a space between adjacent second insulation panels; a lower fastening structure fixed on the hull, and connected to the tension spring, and fixing the second lower plywood; and an upper fastening structure connected to the tension spring, and fixing the second wall and the first lower plywood. The present invention aims to provide a membrane-type liquefied gas storage tank and a vessel comprising the same, which are capable of reducing the cost.
