Provided is a method of manufacturing plate-like members whereby shape defects in the plate-like members can be prevented to increase production yield and a laminate for use in the method of manufacturing plate-like members. A method of manufacturing a plurality of plate-like members by breaking a base materialfor plate-like members into segments includes the steps of: preparing a base materialfor plate-like members having a first principal surfaceand a second principal surfaceopposed to each other; forming a breaking groovein the first principal surfaceof the base materialfor plate-like members; bonding a support filmto the second principal surfaceof the base materialfor plate-like members; bonding an adhesive filmto the first principal surfaceof the base materialfor plate-like members to cover the first principal surfaceof the base material; and breaking the base materialfor plate-like members into segments along the breaking grooveby pressing, through the support filmand with the adhesive filmbonded to the base materialfor plate-like members, a region of the base materialfor plate-like members where the breaking grooveis formed.

Provided is a manufacturing method for a thin phosphor glass plate by which a thin phosphor glass plate can be more certainly produced. A manufacturing method includes the steps of: preparing a phosphor glass base materialhaving a first principal surfaceand a second principal surfaceopposed to each other; placing the phosphor glass base materialon a stageand fixing the second principal surfaceonto the stage; and polishing the first principal surfaceof the phosphor glass base materialwith a polishing memberincluding an abrasive layer

Manufacturing method for phosphor glass thin plate and piece thereof, and phosphor glass thin plate and piece thereof

Provided are a method for manufacturing wavelength conversion members that enables manufacturing of wavelength conversion members having a high light extraction efficiency and suppression of material loss, a wavelength conversion member obtained by the method, and a light-emitting device. A method for manufacturing a plurality of wavelength conversion members by breaking into parts a base materialfor the wavelength conversion members includes the steps of: preparing the base materialhaving a first principal surfaceand a second principal surfaceopposed to each other; forming a breaking groovein the first principal surface; bonding a supportto the second principal surfaceof the base materialhaving the breaking grooveformed in the first principal surface; pressing through the supporta region of the base materialwhere the breaking grooveis formed, thus breaking the base materialinto the plurality of wavelength conversion members along the breaking groove; expanding the supportto form a gap between the plurality of wavelength conversion members lying on the support; and removing the plurality of wavelength conversion members from the supportafter forming the gap.
