섬유 집합체로 이루어지는 심재(10)를 외포재(20, 21)로 피복하고, 외포재(20, 21)의 내부를 감압하기 전에, 심재(10) 및 외포재(20, 21)를 외력으로 일체로 압축하여, 심재(10)의 두께가 압축 전의 1/10 이하가 되는 압축 상태로 하고, 압축 상태에서, 외포재(20, 21)의 주연부 중 적어도 상대하는 2변에 용착 실부(40)를 형성하고, 용착 실부(40)를 형성한 후에, 외포재(20, 21)의 내부를 감압하여 밀봉한다. The present invention involves covering a core material (10) comprising a fiber assembly with outer packaging (20, 21), and before depressurizing the interior of the outer packaging (20, 21), compressing the core material (10) and the outer packaging (20, 21) into one body by applying external force, and compressing to a compressed state in which the thickness of the core material (10) is 1/10 or less the thickness before compression, and then, while in the compressed state, forming weld-sealed sections (40) on at least two facing sides of the peripheral edge sections of the outer packaging (20, 21), and after forming the weld-sealed sections (40), depressurizing and sealing the interior of the outer packaging (20, 21).
