Zusammenfassung:	A waterproof structure of the present invention is for an electronic device including a housing including a first case member that has a first abutting face, and a second case member that has a second abutting face that faces the first abutting face. A water repellent treatment is applied to the first and second abutting faces, and two or more boundaries that change from a region having a relatively small liquid droplet contact angle to a region having a relatively large liquid droplet contact angle are provided along a liquid infiltration direction at an abutting ends portion of the first and second case members.
