Further, the welded portion 5 is integrally formed over the upper and lower main body plate members 2 and 3, and the upper and lower main body plate members 2 and 3 are integrally formed.
Are joined by the welding portion 5. The material of the main body plate members 2, 3 melted to form the welding hole 4 melts into the peripheral portion of the welding hole 4, that is, flows into the welding portion 5. Therefore, the welded portion 5 is in a high-density state in which the density is higher than the density of the foam before melting. The density is higher as the position is closer to the welding hole portion 4, and the density decreases as the position increases. Therefore, the boundary of the welded portion 5 may not be clear.
