We performed $^{17}$O nuclear magnetic resonance measurements onsuperconducting (SC) Sr$_2$RuO$_4$ under in-plane magnetic fields. We foundthat no new signal appears in the SC state and that the $^{17}$O Knight shiftsobtained from the double-site measurements remain constant across thefirst-order phase-transition line, as well as across the second-orderphase-transition line as already reported. The present results indicate thatthe SC spin susceptibility does not decrease in the high-field region, althougha magnetization jump in the SC state was reported at low temperatures. Becausethe spin susceptibility is unchanged in the SC state in Sr$_2$RuO$_4$, wesuggest that the first-order phase transition across the upper critical fieldshould be interpreted as a depairing mechanism other than the conventionalPauli-paramagnetic effect.
