A glass frit includes a glass which contains: Li; at least one selected from the group consisting of B, Si, P, Ge, and Te; O; and at least one selected from the group consisting of F, Cl, Br, and I. The glass is to turn into a crystallized glass including an amorphous phase and a crystalline phase, the crystalline phase precipitated by a heat treatment at a temperature equal to or higher than a glass transition temperature and equal to or lower than a glass crystallization temperature. The crystallized glass shows diffraction peaks at 2θ=22.8±0.5°, 2θ=32.1±0.5° and 2θ=39.6±0.5° in a powder X-ray diffraction pattern using Cu-Kα radiation.
