To facilitate maintenance work.SOLUTION: A cooling device includes a metal member 501 that is thermally coupled with a plurality of elements that generate heat, a water-cooled jacket 503 formed with a flow path 531 through which a refrigerant flows inside, and a heat conductive sheet 502 arranged between the metal member 501 and the water-cooled jacket 503, and the heat conductive sheet 502 has an adhesive surface 502a and a non-adhesive surface 502b, the adhesive surface 502a is adhered to the metal member 501, and the non-adhesive surface 502b is pressed and is thermally coupled with the water-cooled jacket 503 so as to be in contact with the water-cooled jacket 503, such that the heat conductive sheet 502 and the water-cooled jacket 503 can be separated from each other.SELECTED DRAWING: Figure 14 【課題】保守作業を容易にする。【解決手段】発熱を生じる複数の素子と熱結合する金属部材５０１と、内部に冷媒が流れる流路５３１が形成された水冷ジャケット５０３と、金属部材５０１と水冷ジャケット５０３との間に配置された熱伝導シート５０２とを備え、熱伝導シート５０２は、粘着性がある粘着面５０２ａと非粘着性の非粘着面５０２ｂとを有し、粘着面５０２ａは、金属部材５０１に粘着され、非粘着面５０２ｂは、押圧されて水冷ジャケット５０３と接触して熱結合しており、熱伝導シート５０２と水冷ジャケット５０３とが分離可能である。【選択図】図１４
