PROBLEM TO BE SOLVED: To provide a jig for inspecting the thickness of rigid urethane foam, which can easily inspect the thickness of rigid urethane foam formed in-situ. SOLUTION: The jig for inspecting the thickness of rigid urethane foam formed by spraying and foaming a concentrated rigid urethane foam liquid on a wall surface includes: a measuring needle 2 for puncturing a rigid urethane foam layer B; a main body 1, having a measuring surface 1c capable of making contact with the rigid urethane foam layer B, which supports the measuring needle 2 so that a tip of the measuring needle 2 protrudes from the measuring surface 1c by a predetermined length; an ink guide 1a provided on the tip so as to include the measuring surface 1c of the main body 1; and an ink container 1b, disposed next to the ink guide section 1a of the main body 1, which contains ink to be supplied to the ink guide 1a. The ink adheres to a surface Q of the rigid urethane foam layer B when the measuring needle 2 punctures the rigid urethane foam layer B and the measuring surface 1c makes contact with the rigid urethane foam layer B.
