The present inventive concept relates to a lead wire connector and a solenoid valve including the same, the lead wire connector preventing the inflow of foreign substances containing water, facilitating a layout design for coupling and separation, and being conveniently transported and stored. The lead wire connector comprises: an insulation block protruding to the outside of a solenoid; a power terminal provided inside the insulation block and electrically connected to the solenoid; a lead wire connected to the power terminal and extended to the outside of the insulation block; a wire tube encompassing at least a part of the lead wire; and a connector provided at the end of the lead wire. In addition, the solenoid valve includes the solenoid operated according to whether electric power is applied thereto.
