Abstract
Provided are a composite type heat insulator having an excellent heat insulating properties at high temperatures regardless of its thin body, and a method for producing the same. The composite type heat insulator comprises a first and a second cloths composed of silica fibers having a hydroxyl group; and a heat insulating layer sandwiched between the first and the second cloths. The heat insulating layer contains a silica aerogel and silica staple fibers having a fiber length of 0.5 to 5 mm. The heat insulating layer may optionally contain an infrared absorber and/or a film-forming inorganic binder.
