The present invention relates to a high-voltage submersible motor and a waterproof connector for use in the submersible motor. The submersible motor includes a motor body (36), a power cable (37a), a cable contact (50) electrically connected to the power cable (37a), a cable-side insulating member (49) to which the cable contact (50) is liquid-tightly coupled, a motor contact (42) connected to the cable contact (50), a motor-side insulating member (41) to which the motor contact (42) is liquid-tightly coupled, and an insulating resin (93) that fills an enclosed space (60) formed between the cable-side insulating member (49) and the motor-side insulating member (41). A connecting portion of the cable contact (50) and the motor contact (42) is covered with the resin (93).
