The element pair 62 and the element pair 64 are housed in one module and configured as a 2-in-1 module in a manner that the first element pair operates as a positive side arm of the power converting apparatus and the second element pair operates as a negative side arm of the power converting apparatus. The element pairs 62 and 64 are formed such that a ratio of an occupied area of SiC-FWD chips to an occupied area of IGBT chips in the element pairs 62 and 64 is equal to or higher than 15% and lower than 45%.",
