PROBLEM TO BE SOLVED: To provide an inexpensive drain means capable of completely preventing intrusion of, especially, a cockroach, and preventing the strength of a synthetic resin case from being deteriorated without damaging the molding of the case for water electric equipment such as an alkali ion water generator. SOLUTION: A case made of synthetic resin is provided with a fluid passage and an electric part, and a drain means for ejecting leaking water from the fluid passage to the outside of the case is formed at the lower part of the case in this electric equipment. The water drain means is constituted of plural drain holes whose lower openings are widely opened in a tapered shape with small diameter parts whose diameters are ranging from 0.5 to 1.5 mm, and the mutual opening edges of the adjacent openings are overlapped or tightly fitted.
