Abstract: A method for manufacturing a component made of a hard brittle material includes: a step of preparing a base material made of a hard brittle material; and a step of embossing the base material. A protrusion protruding in a first direction and a bottom surface surrounding the protrusion are formed on the base material by the embossing. The bottom surface extends in a plane defined by a second direction intersecting the first direction and a third direction intersecting the first direction and the second direction. The bottom surface and a side surface of the protrusion continuous with the bottom surface satisfy a relationship of z=Ax2−Bx in a cross section defined by the first direction and the second direction when the first direction is represented by z and the second direction is represented by x. A is 0.005 to 0.200 and B is 0.050 to 0.955.
