WIRE HARNESS MANUFACTURING METHOD, WIRE HARNESS, PROTECTIVE MEMBER ASSEMBLY, AND PROTECTIVE MEMBER

A wire harness manufacturing method includes: an insertion step (S1) of inserting a binding member through an insertion hole of a protective member; a temporary retention step (S2) of inserting the binding member through a temporary retention notch in a state where the binding member is inserted through the insertion hole, and hooking the binding member, which is in a state of being inserted through the temporary retention notch, to the temporary retention projection to achieve temporary retention of the binding member on the temporary retention projection; a routing step (S3) of routing a wiring member in a routing space in a state where the binding member is temporarily retained on the temporary retention projection; and a binding step (S4) of detaching the binding member.
