Abstract: A plate-like glass includes a chemically strengthened glass having a first surface, a second surface facing the first surface, and an end surface connecting the first surface and second surface. When a tangential direction from an arbitrary point on the first surface is assumed to be an X-axis, a direction orthogonal to the X-axis is assumed to be a Y-axis, and a direction orthogonal to the X-axis and the Y-axis is assumed to be a Z-axis, the X-axis is a direction in which a first curvature radius R1 in cross-section of the first surface in an XZ plane passing the X-axis and Z-axis is minimum. The first surface has a curvature part in which the surface is bent in the X-axis direction on the first surface and the first curvature radius R1 is within a specific range.
