Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a bolt inspection device, capable of inspecting a whole bolt shaft stably and with a high sensitivity, by simply applying a probe to the head of a bolt. SOLUTION: A complex probe 12-2 is mounted on the bolt head. The complex probe 12-2 has 12 periphery vertical vibrators 1ch-12ch arranged in a circle in viewing the head in the bolt axis direction in the condition of being mounted to the bolt head. A controller of the bolt inspection device sequentially selects groups consisting of 3 periphery vertical vibrators mutually contiguously arranged, from the 12 periphery vertical vibrators of the complex probe 12-2. A transmitter and receiver of the bolt inspection device receives an echo via the three periphery vertical vibrators activated by activating all three of the periphery vertical vibrators included in the selected group at each time when the group is selected by the controller.
