1. A phosphor substrate having at least one light emitting element mounted on one surface, the phosphor substrate comprising:
an insulating substrate;
an electrode layer disposed on one surface of the insulating substrate and bonded to the light emitting element; and
a phosphor layer which is disposed on one surface of the insulating substrate and includes a phosphor in which a light emission peak wavelength, in a case where light emitted by the light emitting element is used as excitation light, is in a visible light region,
wherein a bonded surface of a surface of the electrode layer facing an outer side in a thickness direction of the insulating substrate, the bonded surface being bonded to the light emitting element, is positioned further on the outer side in the thickness direction than a non-bonded surface which is a surface other than the bonded surface, and
at least a part of the phosphor layer is disposed around the bonded surface.
