PROBLEM TO BE SOLVED: To provide a unit for mounting a power element which has superior cooling performance and can execute miniaturization and space saving for an apparatus, and to provide a manufacturing method of the unit for mounting a power element and a power module. SOLUTION: The unit 7 for mounting a power element is constituted so that a cooling liquid C circulating in an apparatus can recover heat and cool the apparatus. In the power unit 7, two separated headers 1a, 1b through which the cooling liquid C circulates and a multi-flow passage pipe 2 having both ends supported between the headers 1a, 1b and allowing the cooling liquid C to circulate are each differently disposed side by side in plane; and the power unit 7 is provided with a ceramic insulating layer 52 directly jointed to one surface of the multi-flow passage pipe 2; and a circuit layer 51 provided on the one surface of the ceramic insulating layer 52.
