PROBLEM TO BE SOLVED: To provide a portable nondestructive inspection device capable of heat-exchanging efficiently heat of a heat generation part inside a housing with an outside, without impairing sealability for the housing. SOLUTION: A grip part 8 grasped by a worker is formed of a metal material integrally with the housing 2, and a slit groove 9 for heat radiation is formed in the grip part 8. Heat transfer from a substrate 14 inside the housing 2 to the grip part 8 is promoted by a fan 15a. COPYRIGHT: (C)2006,JPO&NCIPI
