A method of manufacturing a glass bent sheet includes a printing step (S1), a provisional sintering step (S2), and a crystallization step (S3). In the printing step (S1), a paste including glass powder that contains an alkali metal oxide as a component and a pigment is printed onto a flat sheet-shaped glass substrate formed of a LAS-based crystallizable glass. After the printing step (S1) and before the crystallization step (S3), in the provisional sintering step (S2), the paste printed onto the glass substrate is heated at a temperature equal to or higher than a softening point of the glass powder plus 20C and lower than the highest heating temperature in the crystallization step (S3). In the crystallization step (S3), the glass substrate having the paste printed thereon is subjected to bending work by heating, and the crystallizable glass is crystallized by heating.
