The light source device for an endoscope includes a first solid-state light-emitting element, first and second phosphors, light in a first wavelength band emitted from the first solid-state light-emitting element, and first phosphor A light source unit that emits irradiation light including first fluorescence emitted from the second fluorescent material and second fluorescence emitted from the second phosphor, and at least one wavelength that transmits only light in a specific wavelength band of the irradiation light The limiting filter and the wavelength limiting filter are configured from filter insertion / extraction means that supports the optical path of the irradiation light so as to be inserted / extracted. When the wavelength limiting filter is inserted into the optical path, the irradiation light is filtered into the light including the first wavelength band and the light including the second fluorescence and supplied to the endoscope. When the wavelength limiting filter is removed from the optical path, the irradiation light is supplied to the endoscope without being filtered.内視鏡用光源装置を、第１の固体発光素子、第１及び第２の蛍光体を有し、第１の固体発光素子から射出される第１の波長帯域の光、第１の蛍光体から発せられる第１の蛍光、及び第２の蛍光体から発せられる第２の蛍光を含む照射光を射出する光源部と、照射光のうち特定の波長帯域の光のみを透過させる少なくとも１つの波長制限フィルタと、波長制限フィルタを、照射光の光路に対して挿抜可能に支持するフィルタ挿抜手段とから構成する。波長制限フィルタが光路に挿入されると、照射光が、第１の波長帯域の光と第２の蛍光を含む光にフィルタリングされて内視鏡に供給される。波長制限フィルタが光路から抜去されると、照射光がフィルタリングされることなく内視鏡に供給される。
