The symbiotic nature of this object has been investigated by optical spectroscopy and photometry in the near infrared region. There are three components, which are (i) the ionized expanding envelope consisting of two layers of low and high excitation species, (ii) the late type component corresponding to a blackbody of 2500 K and indicated by TiO absorption band, (iii) the hot remnant star whose temperature is estimated indirectly as 150 000 K or more.
