PROBLEM TO BE SOLVED: To provide a deep hole machining method by which a deep hole with breakage can be immediately verified after the completion of machining all of the deep holes while all deep holes are continuously formed, and a deep hole machining device. SOLUTION: The deep hole machining method includes: a tool failure detecting step ST13 of detecting a failure of a gun drill; a breakage determination step ST16 of determining whether or not the gun drill breaks when the failure of the gun drill is detected; a deep hole machining continuation step of continuing to machine the deep hole at a current machining position when the failure is determined not to be the breakage of the gun drill; breakage control steps ST17 and 18 of replacing the gun drill mounted to a spindle with a new gun drill when the breakage of the gun drill is determined and also writing information that the deep hole machining at the current machining position has the breakage of the gun drill into a breakage machining list; and a list output step of outputting the breakage machining list when deep hole machining at all of machining positions is completed.
