A wide-band RF signal power detecting element includes, on an insulating substrate (21), at least one thin-film resistor (22a) for absorbing the power of a signal to be measured and generating heat, first and second ground electrodes (27, 28) formed by thin-film conductors, a first thin-film connecting portion (24) for electrically connecting the first ground electrode (27) to the thin-film resistor (22a), a second thin-film connecting portion (25) for electrically connecting the second ground electrode (28) to the thin-film resistor (22a) and narrowing the gap between the first and second thin-film connecting portions (24, 25) toward the thin-film resistor (22a), and an input electrode (26) formed between the first and second ground electrodes (27, 28) and electrically connected to the thin-film resistor (22a). <IMAGE> |
