Provided is compatibility between adhesion to a substrate (lower layer) and durability improvement. An optical element includes a phosphor layer facing a lower layer, and a bonding layer keeping the phosphor layer in intimate contact with the lower layer. The phosphor layer includes an inorganic binder, and phosphor particle dispersed with the inorganic binder. The bonding layer includes an organic binder. The phosphor layer has a first surface facing the lower layer, a second surface opposite to the first surface, and a side surface connecting the first and second surfaces together. The bonding layer connects together the second surface, the side surface, and a surface of the lower layer to keep the phosphor layer in intimate contact with the lower layer.
