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 r |
