PROBLEM TO BE SOLVED: To provide a cooling device capable of improving cooling efficiency of a heating element.SOLUTION: A cooling type cooling device includes: a box-shaped airtight case in which an introduction port and a discharge port of cooling water are provided; and a plate-shaped cooling fin which is erected on an internal wall surface of the airtight case so that a long side becomes parallel to the flow direction of the cooling water. The plurality of cooling fins are provided in the direction orthogonal to the flow direction of the cooling water. A part or all of a columnar component included between the adjacent cooling fins is erected on the internal wall surface on which the cooling fins are provided or the internal wall surface opposite to this internal wall surface out of the internal wall surface of the airtight case. |
