The design and performance of imaging gas scintillation proportional counters (IGSPCs) developed for ASTRO-D are described. The 10 micrometers beryllium window has enabled the x- ray sensitivity down to 0.7 keV for a sealed-off gas counter, and a position-sensitive phototube equipped with multiwire anode gives good imaging capability. The laboratory model of the IGSPC shows an energy resolution 8% FWHM at 6 keV and a position resolution 0.5 mm FWHM with an effective area of 50 mm diameter. The onboard data system incorporating a 16-bit microprocessor efficiently discriminates the room background down to the order of magnitude of 3 X 10(superscript -4) cm(superscript -2) s(superscript -1) keV(superscript -1), similar to that achieved by the Ginga LAC instrument. These performances make the GIS experiment a very powerful focal plane instrument for ASTRO-D.
