PROBLEM TO BE SOLVED: To provide an LED light source unit capable of achieving reduction in the number of assembly man-hours, and a lighting fixture.SOLUTION: An LED substrate 1 is arranged on a light source mounting plate 2 in a state where a positioning through-hole 1a and a positioning through-hole 2a are mutually aligned, and a positioning projection part 33a of a lens unit 3 is inserted in the positioning through-hole 1a of the LED substrate 1 and the positioning through-hole 2a of the light source mounting plate 2, the LED substrate 1 and the lens unit 3 are positioned with respect to the light source mounting plate 2, and furthermore, in a state where a peripheral edge part of an opening part 41 of a light source cover 4 is brought into contact with a peripheral edge part (step part 31b) on a front side of the lens unit 3, the light source cover 4 is fixed to the light source mounting plate 2 with a fixing member (spacer 5 and screw 6). With this structure, work for screwing the LED substrate 1 to the light source mounting plate 2 becomes unnecessary, and the number of assembly man-hours can be reduced.SELECTED DRAWING: Figure 5 【課題】組立工数の低減化を図ることが可能なＬＥＤ光源ユニット及び照明器具を提供する。【解決手段】ＬＥＤ基板１を光源取付板２に、位置決め貫通孔１ａと位置決め貫通孔２ａとを相互に位置合せした状態で配置し、レンズユニット３の位置決め突部３３ａをＬＥＤ基板１の位置決め貫通孔１ａ及び光源取付板２の位置決め貫通孔２ａに挿入することにより、光源取付板２に対してＬＥＤ基板１及びレンズユニット３を位置決めし、さらに、光源カバー４の開口部４１の周縁部をレンズユニット３の前面側の周縁部（段部３１ｂ）に当接させた状態で、当該光源カバー４を光源取付板２に固定部材（スペーサ５及びビス６）にて固定する。このような構造とすることにより、ＬＥＤ基板１を光源取付板２にねじ止めする作業が不要となり、組立工数を低減することができる。【選択図】図５
