In a wire electric discharge machine in which the processing liquid exists between a wire electrode 2 and a work piece 3, and the work piece 3 is processed while the discharge is being generated, the wire electric discharge machine has a jetting nozzle 140 to jet the processing liquid to the work piece 3, and a wire guide portion to flow the processing liquid to the jetting nozzle 140 and to guide the wire electrode 2 into a bored hole, and the wire guide portion has the first passage 133b to flow the processing liquid into the jetting nozzle, and the second passage 131b to convert the direction of the processing liquid to be flowed into the first passage 133b.
