The prior art has a problem in which an isolation between output terminals is deteriorated when a thin film resistor is used as an isolation resistor. Such being the case, in a power divider/combiner comprising an input terminal, two output terminals, two branch lines each connecting the input terminal and one of the output terminals and having a line length that is ¼ of a set wavelength or a multiple of integer of half a wavelength and ¼ of the set wavelength, and an isolation resistor connected to between the output terminals, there is provided an improved power divider/combiner further comprising a transmission line interposed between each of the output terminals and the branch lines. Consequently, even when using the isolation resistor having a length that can not be ignored as compared with a wavelength of a high-frequency signal in use, the isolation between the output terminals can be ensured.
