Abstract:
This electronic device actively drains water which has entered into a through-hole of a printed wiring board. A connector unit 100 is provided with: a printed wiring board 30 comprising a circular through-hole 31b penetrating through an upper surface 30A and a lower surface 30B; an electronic component 40 mounted on the upper surface 30A; a water guiding member 20 which is disposed on the lower surface 30B side and at least a portion of which faces the through-hole 31b; and a case 70. The water guiding member 20 has, at a portion facing the through-hole 31b, a projection shape (tip 203) or a surface (surface 231b) inclined in a direction away from the lower surface 30B, and the portion is disposed such that the shortest distance to the gravity center of the shape of an end 31b2 is shorter than the radius of the largest circle insertable into the shape of the end 31b2.
