PROBLEM TO BE SOLVED: To provide a light source unit in which reduction of an irradiation light quantity to a lighting space side is suppressed, and lighting equipment using the light source unit.SOLUTION: A reflection member 26 has a cylindrical shape and is arranged so as to surrounds the periphery of a lens 22 mounted on a mounting member 23 and reflects the light having passed through the lens 22, on an inner peripheral surface 2611. A heat radiation member 24 includes: a bottom wall part 241; and side wall parts 242 to 245 protruding from the end part of the bottom wall part 241 in a direction of intersecting the bottom wall part 241. A base plate 21, the lens 22, the mounting member 23 and the reflection member 26 are arranged in a space surrounded by the bottom wall part 241 and the side wall parts 242 to 245. The mounting member 23 and the reflection member 26 have insertion pieces 263 or insertion grooves 2318a to 2320a for integrally joining the mounting member and the reflection member to each other.SELECTED DRAWING: Figure 1 【課題】照明空間側への照射光量の低下を抑えた光源ユニット及びそれを用いた照明器具を提供する。【解決手段】反射部材２６は、筒状であって、取付部材２３に取り付けられたレンズ２２の周囲を取り囲むように配置され、レンズ２２を透過した光を内周面２６１１で反射させる。放熱部材２４は、底壁部２４１と、底壁部２４１の端部から底壁部２４１と交差する方向に突出する側壁部２４２〜２４５とを有する。基板２１、レンズ２２、取付部材２３及び反射部材２６は、底壁部２４１と側壁部２４２〜２４５とで囲まれる空間内に配置される。取付部材２３及び反射部材２６は、互いを一体的に結合させる差込片２６３又は差込溝２３１８ａ〜２３２０ａを有する。【選択図】図１
