PURPOSE:To reduce the stress at the end part of a case by reducing not only the use amount of an adhesive but also the generation of heat of said adhesive, by forming an adhesive sealed end part by adhering and sealing an adhesive in a small amount stepwise to cure the same to form a multilayered adhesive part in the lingitudinal direction of a module. CONSTITUTION:In adhering and sealing the end part of a hollow yarn membrane module wherein hollow yarns 1-1 are allowed to fill a case 3-3, an adhesive is divided into plural times, that is, two times or more and adhered and sealed in a small amount to form a multilayerd adhesive sealed part 5-5. By this method, one time of heat generating quantity at every sealing is reduced and heat generating irregularity is reduced to make release hard to generate. Because the adhesive layer becomes thinner each time the shrinkage at the time of curing becomes easy to generate not only in a radius direction but also in the longitudinal direction of the module and residual shrinkage is reduced and a heat resistant hollow yarn membrane module capable of withstanding thermal shock can be formed.
