INTEGRAL made 3 observations in 2003 April of the black hole candidate H 1743-322 during the rising part, and close to the maximum, of an outburst. H 1743-322 was previously observed in outburst in 1977-1978. The source is located in a crowded region of the sky (l=357°, b=-2°) and at least 18 sources are clearly detected in the field of view of the ISGRI gamma-ray imager during a 277ks exposure. These are well known persistent X-ray binary sources and 3 transient sources in outburst. The combined 5-200keV JEM-X and SPI spectrum of H 1743-322 is well fit with an absorbed ((2.5^+4.3_–2.5)x10²²atom/cm2) soft (photon index 2.70±0.09) power-law model, consistent with H 1743-322 being in a high/soft state.
