PROBLEM TO BE SOLVED: To obtain a masking jig for a hole part capable of being rapidly attached to and detached from a work and usable repeatedly. SOLUTION: A heat-resistant holding element (2) is provided so as to move a pair of opposed holding pieces (3a) in a mutually approaching direction by the reaction of an elastomer (5) and a heat-resistant masking object (10) for closing the hole part (21) of the work (20) is provided to at least one of holding pieces (3a). The masking object (10) is formed as the plate material coming into contact with the outer peripheral edge part of the hole part (21) of the work (20) and a guide (11) fitted to the hole part (21) is provided on the contact surface side of the plate material.
