To provide a water passage device which can detect a sign of liquid leakage, a water-cooling cooler including the water passage device, and an electric power conversion device including the water-cooling cooler.SOLUTION: In a water passage device 120 of an electric power conversion device 100, a first structure 140 and a second structure 142 respectively have a first joint surface 150 and a second joint surface 152. The first joint surface 150 is joined to the second joint surface 152. The first structure 140 and the second structure 142 form a water passage. A first conductor line 132a, an insulator layer, and a second conductor line 132b are disposed between the first joint surface 150 and the second joint surface 152. The second conductor line 132b contacts with the first conductor line 132a through the insulator layer. The insulator layer has a water passing path penetrating therethrough in a thickness direction. An electric circuit detects electric conduction between the first conductor line 132a and the second conductor line 132b.SELECTED DRAWING: Figure 1
