摘要： An object is to closely observe, by means of images of a camera having high performance specifications, changes in a structure due to heating or cooling of the structure to a temperature beyond a service temperature limit of the camera having high performance specifications and returning from that temperature to room temperature. A structure observation device includes: a camera case of a rectangular three-dimensional shape, having a glass window of heat-resistant and/or cold-resistant glass on at least one side of the three-dimensional shape; heat insulating walls covering the camera case except for the glass window; a fluid supply port and a fluid discharge port through which a cooling or warming fluid is circulated into; and a camera that is disposed inside the camera case and captures a still image or a moving image through the glass window and externally outputs or internally stores data of the captured image.
