An electronic device includes a body frame formed by mating first to third members. The first and second members each include first to third mating surfaces. The first and second mating surfaces face corresponding surfaces in a first direction and the third mating surfaces face each other in a second direction orthogonal to the first direction. The first to third members each include fourth to sixth mating surfaces. Between the first and second members and the third member, the fourth and fifth mating surfaces face corresponding surfaces in a third direction orthogonal to the first and second directions, and the sixth mating surfaces face each other in the second direction. Microstructures for a liquid repellency are provided on at least one of the first to third mating surfaces and at least one of the fourth to sixth mating surfaces.
