PROBLEM TO BE SOLVED: To provide a light emitting device achieving high illuminance, and to provide an illumination lamp and a lighting device.SOLUTION: A light emitting device includes: a first laser beam source 11 which emits a first laser beam; a second laser beam source 12 which emits a second laser beam having a wavelength different from that of the first laser beam; a multiplex part 31A which multiplexes the first laser beam emitted from the first laser beam source 11 and the second laser beam emitted from the second laser beam source 12; a first light guide part 30 into which the first laser beam and the second laser beam multiplexed by the multiplex part 31A enter, the first light guide part 30 which transmits the first laser beam and the second laser beam between a first surface 33a and a second surface 33B facing each other; and a reflection part 32 which is provided at the first surface 33A side and reflects the first laser beam and the second laser beam to the second surface 33B side.SELECTED DRAWING: Figure 4 【課題】高照度の発光装置、照明ランプおよび照明装置を得る。【解決手段】第１レーザ光を出射する第１レーザ光源１１と、第１レーザ光とは異なる波長の第２レーザ光を出射する第２レーザ光源１２と、第１レーザ光源１１から出射された第１レーザ光と、第２レーザ光源１２から出射された第２レーザ光とを合波する合波部３１Ａと、合波部３１Ａが合波した第１レーザ光および第２レーザ光が入射され、互いに対向する第１面３３Ａと第２面３３Ｂとの間で、第１レーザ光および第２レーザ光を伝搬する第１導光部３０と、第１面３３Ａ側に設けられ、第２面３３Ｂ側に、第１レーザ光および第２レーザ光を反射する反射部３２と、を有することを特徴とする。【選択図】図４
