    Si-PIN photodiode type detector is one of the X-ray detectors which have recently shown significant improvement in resolution of FWHM of 250 eV at 5.9 keV which is worse only by 130 eV than that of a conventional type Si(Li) detector. The remarkable advantages of the SPINP detector are high operability with the thermoelectric cooling system and low voltage bias, and small volume including the preamplifier system. It is found that SPINP detector is applicable to the X-ray spectrometry and also PIXE in the X-ray energy range below about 15 keV with a reasonable efficiency. The pattern analysis method is feasible to analysis such bad resolution spectra obtained with this detector. Some techniques related to the Si-PIN photodiode type detector in Bio-PIXE are discussed.
