Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent corrosion of a joint part having a complicated shape such as a three way joint for joining tubes of dissimilar metals.SOLUTION: The electrochemical corrosion of a pipe joint part having the complicated shape such as the three way joint formed of the dissimilar metal tubes is prevented by covering the joint part with a corrosion-proof sheet having a film layer formed by dispersing an ionic exchange resin for capturing ion which becomes corrosion factor on an adhesive sheet having thermal adhesiveness and heating and melting the sheet to prevent intrusion of water or ions to become the corrosion factor. Heat insulating material or a hygroscopic material using a urethane foam is used.
