PURPOSE: A sealing method and a sealing element are provided which is capable of quickly and easily sealing gap between a diameter of a different through guide passage and an object inserted into this through guide passage in sealing the through guide passage and imposing no burden on an environment. CONSTITUTION: In a sealing method for sealing a gap(4) between the through guide passage(2) arranged in a structural element(1) and the object(3) inserted into at least this one through guide passage(2) by arranging at least one sealing element(5), a thermally melting element(5) including at least one temperature activating expansive medium is used as the sealing element(5), and after filling this thermally melting element(5) in the clearance(4), the element is melted and expanded by adding heat from the outside to be hardened to completely seal the clearance. Bar-shaped thermally melting elements(5) are suitably inserted and filled in large numbers in the clearance(4).
