HEAT INSULATOR A heat insulator (2) includes a first covering part (21) and a second covering part (22). The first covering part (21) is configured to cover a bent part (12) formed in an exhaust pipe (1) of an internal combustion engine. The first covering part (21) has a plurality of slits (41, 42) extending in a circumferential direction of the exhaust pipe (1). The plurality of slits (41, 42) are arranged with a given space from each other in a direction in which the exhaust pipe (1) extends such that a plate part between slits (43) is present between the plurality of slits (41, 42). The second covering part (22) covers the other part of the exhaust pipe (1) than the bent part (12). At least a part of the second covering part (22) is bonded to the exhaust pipe (1).
