Abstract
A crack detection device for detecting a crack that occurs in a structure, includes: an MI cable that includes a metal sheath and a conductive wire accommodated in the metal sheath via a mineral insulating powder, and that is disposed along the structure so as to intersect an assumed crack C in a part of the structure where occurrence of a crack is assumed; a joint portion that is made of a metal that forms a joint when solidified from a melting state, and that joins the MI cable to the structure or a member fixed to the structure; and a detection device connected to both ends of a conductive wire, and configured to detect electrical characteristics of the conductive wire. The joint portion is present on one side and the other side with respect to the assumed crack C in a direction intersecting the assumed crack C.
