Abstract: A funnel glass containing PbO for a cathode ray tube, wherein when the composition is represented by wt % based on oxides, the content of SrO is at least 1.0 wt %, the content of BaO is at least 1.0 wt %, and the ratio of the content of PbO to the total amount of PbO, SrO, BaO, CaO and MgO, is at most 0.69, and whereby the lead elution A of the glass as measured by the following method A is at most 1.0 &mgr;g/cm2, and the X-ray absorption coefficient at a wavelength of 0.6 Å is at least 40 cm−1: Method A: The glass is immersed in distilled and deionized water at 90° C. for 20 hours, whereupon the glass is taken out, and the amount of lead in the distilled and deionized water is measured by inductively coupled plasma emission spectrometry, and the measured value of the amount of lead is divided by the surface area of the glass, and the product is taken as the lead elution A.
