A lighter includes a housing having a through-hole defined by an annular wall. The annular wall has a thickness smaller than that of the remaining portion of the housing. A ring is attached to the through-hole for attaching keys. The annular wall has a central bulge portion, thereby having a maximum diameter in each of two outer portions of the through-hole and a minimum diameter in a central portion of the through-hole. The maximum diameter of the through-hole is greater than a diameter of a cigarette and the minimum diameter of the through-hole is smaller than the diameter of the cigarette.
