PROBLEM TO BE SOLVED: To provide a small-sized and high-durability power converting device equipped with a cooling means for a semiconductor module constituting a power converting circuit. SOLUTION: The power converting device 1 includes the semiconductor module 10 constituting the power converting circuit, and a cooling tube 20 which forms a flow passage of a refrigerant cooling the semiconductor module 10. The power converting device 1 has a semiconductor laminated unit 2 and a guide unit 50. The semiconductor laminated unit 2 is constituted by laminating cooling tubes 20 in a flat shape and semiconductor modules 10 alternately, and both the ends of each cooling tube 20 are linked with a couple of headers constituting a supply side and a discharge side for the refrigerant. The guide unit 50 has a couple of guide surfaces arranged opposite to a surface and a reverse surface that edges in the lengthwise direction of each cooling tube 20 of the semiconductor laminated unit 2 form across a specified gap along the width.
