A cooling device includes a cooling plate with a bottom wall portion with a lower surface which contacts a heat-generating component, a top wall portion which covers an upper surface of the bottom wall portion, a side wall portion which couples the bottom wall portion and the top wall portion, and an internal space which is surrounded by the bottom wall portion, the top wall portion, and the side wall portion to define a first cooling medium flow passage. The bottom wall portion includes blades on the upper surface. An inlet port or an outlet port is on one end side of the first cooling medium flow passage. An inner peripheral wall of the side wall portion includes a first bent portion which is bent convex inward between ends of the blades and the at least one of the inlet port and the outlet port.
