To provide an analysis device comprising an LED light source which is suppressed in change in a light emission spectrum and amount of light, and can be prevented from forming dew.SOLUTION: An analysis device comprises: an LED light source (excitation light LED 501, phosphor 502, and an LED package 503) generating light with which a sample is irradiated; an LED packaged-substrate 504 in which the LED light source and a temperature sensor 505 are packaged; a lamp house 508 which surrounds a periphery of the LED-packaged substrate 504, and houses the LED-packaged substrate 504; a Peltier element 506 which absorbs heat of the LED packaged-substrate 504, or discharges the heat to the LED-packaged substrate 504; and a control unit which controls an output of the Peltier element 506 in such a manner that temperature to be measured by the temperature sensor 505 becomes higher than a threshold temperature.SELECTED DRAWING: Figure 3 【課題】発光スペクトル及び光量の変化を抑え、且つ結露防止が可能なＬＥＤ光源を備える分析装置を提供する。【解決手段】分析装置は、試料に照射される光を発生するＬＥＤ光源（励起光ＬＥＤ５０１、蛍光体５０２、ＬＥＤパッケージ５０３）と、ＬＥＤ光源及び温度センサ５０５が実装されるＬＥＤ実装基板５０４と、ＬＥＤ実装基板５０４の周囲を取り囲み、ＬＥＤ実装基板５０４を収容するランプハウス５０８と、ＬＥＤ実装基板５０４の熱を吸収又はＬＥＤ実装基板５０４に熱を放出するペルチェ素子５０６と、温度センサ５０５によって測定される温度が閾値温度よりも高くなるようにペルチェ素子５０６の出力を制御する制御部と、を備える。【選択図】図３
