PROBLEM TO BE SOLVED: To obtain an optical element holding device capable of accurately adjusting and positioning an optical element in an optical element holding lens barrel, and an optical equipment having the optical element holding device. SOLUTION: In this optical element holding device having the optical element and the optical element holding lens barrel for holding the optical element, the optical element holding lens barrel has an insertion part in which the optical element is inserted, a butting surface abutting on a plane part provided at the periphery part of the optical element when inserting the optical element in the insertion part, and positioning the optical axis direction thereof, three or more tool holes for positionally adjusting the optical element toward an outside diameter on a plane orthogonal to an optical axis on the periphery of the insertion part, and three or more injection holes for injecting an adhesive provided to be equally divided at positions where an angular phase is different from the tool hole, and the optical element is set so that the diameter of its outer peripheral surface may be smaller and smaller as it is separated in the optical axis direction from the plane part.
