Abstract: Provided is a phosphate glass that has a low melting point and has excellent water resistance while maintaining a glass structure. This phosphate glass PGS has a glass transition temperature Tg lower than 490° C. and contains, in oxide-based mol %, 55-65 [mol %] of P2O5, 10-27 [mol %] of ZnO, 0.5-7 [mol %] of R2O3 ((R2O3 is at least one of Al2O3, Ga2O3, and Y2O3), 0.5-3.5 [mol %] of a lanthanoid oxide L2O3(L2O3 is at least one of La2O3, Ce2O3, Pr2O3, Nd2O3, Pm2O3, Sm2O3, Eu2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3, Er2O3, Tm2O3, Yb2O3, and Lu2O3), and 4-15 [mol %] of X2O (X2O is at least one of Li2O, Na2O, K2O, Rb2O, Cs2O, and Fr2O).

Abstract: There are provided with a plurality of filter materials (2) spaced out in a line and whose filter fiber is exposed on the surface thereof; a capsule (3) arranged between the filter materials (2) and in which content liquid to be used as a flavoring agent or adsorbent is enclosed; shaping paper (4) that covers the filter materials (2) and the capsule (3), connects the filter materials (2) to each other, and includes permeation-preventing material for preventing the permeation of the content liquid; and an adhesion device (5) for adhering the filter materials (2) and the shaping paper (4) to each other in between the filter materials (2) and the shaping paper (4) over the entire circumference of the filter materials (2) and the shaping paper (4).

Abstract: A glass emitting white light in itself, and a light-emitting element and a light-emitting device covered with the glass as stated above are provided. The white light-emitting glass is a glass emitting fluorescence at a region having a wavelength of 380 nm to 750 nm by excitation light with a wavelength of 240 nm to 405 nm, not containing crystal, and containing SnOx (where x=1 to 2, typically x=1 or 2), P2O5, and MnOy (where y=1 to 2, typically y=1 or 2). The light-emitting element and the light-emitting device are made up by covering a main surface of a semiconductor light-emitting element with the glass as stated above.
