An element chip manufacturing method includes a preparation process of preparing a substrate which includes a first surface provided with a bump and a second surface and includes a plurality of element regions defined by dividing regions, a bump embedding process of adhering a protection tape having an adhesive layer to the first surface and embedding. The element chip manufacturing method includes a thinning process of grinding the second surface in a state where the protection tape is adhered to the first surface and thinning the substrate, after the bump embedding process, a mask forming process of forming a mask in the second surface and exposes the dividing regions, after the thinning process, a holding process of arranging the first surface to oppose a holding tape supported on a frame and holding the substrate on the holding tape. |
