Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a tapped hole cooling structure capable of preventing abrasion and deformation of a tapped hole peripheral brick for extracting a solution from the inside of a furnace to its outside and keeping a stable operation of a flash furnace in a high copper regulus grade operation/high load operation. SOLUTION: This tapped hole cooling structure comprises a hollow jacket body 10 inserted and disposed in an opening portion 5b formed on a furnace wall 5a, a water channel 23 in which the cooling water flows, is formed inside of the jacket body 10, a flange portion 13 made of a material of the same quality that of the furnace wall 5a to be welded and joined to the furnace wall 5a, is formed around the jacket body 10, the refractory 30 having tapped holes 2a, 2b for extracting the solution to the outside of the furnace is filled in a spatial portion 10a of the hollow jacket body 10, and the jacket body 10 is formed by joining an inner frame body 11 made of iron and an outer frame body 15 made of copper.
