| 英文摘要 | A wavelength conversion element (1) includes a support member (2) having a supporting surface (2a), and a wavelength converter (4) disposed above the supporting surface (2a). The wavelength converter (4) contains first fluorescent particles (4a) which absorb excitation light (82) and generate fluorescence (second radiation light (91)), and a transparent binder (4b) which bonds the first fluorescent particles (4a), and has a joint surface (7) facing supporting surface (2a), and an incident surface (6) disposed opposite to the joint surface (7), the excitation light entering the incident surface (6). The excitation light (82) and fluorescence are emitted from the incident surface (6). The wavelength converter (4) includes projections (5a). At least part of the projections (5a) is disposed on the incident surface (6). The first fluorescent particles (4a) are partially exposed from vertices of the projections (5a). |
