PROBLEM TO BE SOLVED: To provide a needle and a meter, in which an angle of a reflecting surface for reflecting illumination light supplied from the outside toward a front end part of the needle can be reduced without increasing or generating light transmitted through the reflecting surface and the illumination light reflected toward the front end part by the reflecting surface can be efficiently emitted to the outside.SOLUTION: The needle includes: a first needle member 14 including a first light incidence surface 17 on which illumination light supplied from the outside impinges, a first reflecting surface 18 which reflects the illumination light entering the inside via the first light incidence surface 17, and a first emission surface 19 which emits the illumination light reflected by the first reflecting surface 18 to the outside; and a second needle member 15 including a second light incidence surface 20 on which the illumination light emitted from the first emission surface 19 impinges, a second reflecting surface 21 which reflects the illumination light entering the inside via the second light incidence surface 20, and a second emission surface 22 which emits the illumination light reflected by the second reflecting surface 21 to the outside. The first needle member 14 is made of a polycarbonate resin, and the second needle member 15 is made of an acrylic resin.

    【課題】外方から供給される照明光を指針の先端部側に反射する反射面での透過光を増加又は発生させることなく、反射面の角度を小さくすることを可能にすると共に、反射面で先端部側に反射された照明光を外方に効率的に放出可能な指針及び指示計器を提供する。【解決手段】外方から供給される照明光が入射する第1入光面17と、第1入光面17を通じて内方に進入した照明光を反射する第1反射面18と、第1反射面18で反射された照明光を外方に放出する第1放出面19と、を備える第1指針部材14、及び第1放出面19から放出された照明光が入射する第2入光面20と、第2入光面20を通じて内方に進入した照明光を反射する第2反射面21と、第2反射面21で反射された照明光を外方に放出する第2放出面22と、を備える第2指針部材15を備え、第1指針部材14はポリカーボネート樹脂で構成され、第2指針部材15はアクリル樹脂で構成される。【選択図】図1
