Abstract

See full text

A wavelength conversion member manufacturing method includes providing a wavelength conversion member having an upper surface, and forming, in the wavelength conversion member, at least one depressed portion having an inclined surface inclined with respect to the upper surface by irradiating the wavelength conversion member with a pulsed laser beam from above. The forming of the at least one depressed portion includes performing a set of scanning more than once at different processing depths in regions overlapping each other in a top view, the set of scanning includes performing scanning with the pulsed laser beam along a first direction more than once at irradiation positions shifted in a second direction perpendicular to the first direction in the top view, and the performing of the scanning includes applying the pulsed laser beam at a fixed processing depth.
