PROBLEM TO BE SOLVED: To provide a circuit module which prevents certainly that a cooling medium adheres to the connective material which connects mutually the electric circuits allocated in two or more case members. SOLUTION: A through-hole 31 is bored in a laminated state where an upper side case member 3 having an electric circuit and a lower side case member 5 are brought into contact, and the connective material is allocated in this through-hole 31. The circuit module wherein a channel for cooling media is also formed and a cooling medium is circulated to this channel for cooling media is provided with a sealing member 45 in the periphery of the through-hole 31. Further, in the perimeter side of this sealing member 45, a discharge groove 49 is formed for discharging a cooling medium which infiltrates between both the case members 3 and 5 to the exterior of the case members 3 and 5.
