To provide a mirror unit in which all of external shape of a mirror is covered and nonetheless the mirror can be held by a single component, and to provide a head-up display using the mirror unit.SOLUTION: A mirror unit M of the present disclosure comprises: a trapezoidal mirror 90 forming a reflection surface 90a; and a mirror holder 1 which forms an opening 10 exposing the reflection surface 90a, and covering portions 11, 12, 13 and 14 covering trapezoidal edge portions (an upper bottom 91b, a lower bottom 92b, and legs 93b and 94b). Along the trapezoidal upper bottom 91b, the mirror holder 1 forms: a first energization portion 21 that energizes the lower bottom of the mirror 90 to -Y direction and Z direction; and a hold-back portion 35 that holds back the upper bottom of the mirror 90 toward the Y direction and Z direction. Between the first energization portion 21 and the cover part 12 corresponding to the lower bottom 92b, a space 40s is formed that is enough for causing the upper bottom 91b to be apart in the Y direction from the hold-back portion 35.SELECTED DRAWING: Figure 1A

    【課題】ミラーの外形を全て覆いながらも、ミラーを1つの部品で保持できるミラーユニット及びこのミラーユニットを用いたヘッドアップディスプレイを提供する。【解決手段】本開示のミラーユニットMは、台形状を為し、反射面90aを形成するミラー90と、反射面90aを露出する開口部10と台形状の縁部(上底91b、下底92b、脚93b,94b)を覆う覆い部11,12,13,14とを形成するミラーホルダー1と、を備え、台形状の上底91bに沿い、ミラーホルダー1は、ミラー90の下底を-Y方向及びZ方向に付勢する第一付勢部21と、ミラー90の上底をY方向及びZ方向へ抑える抑え部35と、を形成し、第一付勢部21と、下底92bに対応する覆い部12との間には、上底91bを抑え部35からY方向において離間させるために十分な空間40sを形成する。【選択図】図1A
