Abstract: A small portable flashlight holds laminated platy batteries (11) on a circuit substrate (10) having a switching circuit on one surface thereof and one battery contact point (19) on the other surface thereof. Another battery contact point (22b) is provided on a contact arm (21) extending from the substrate so as to hold the batteries. The batteries, the circuit substrate and contact arm are held in lamination in a flat main body case part (9). A light emitting body (12) having a light emitting part exposed to the outside of the main body case is held on the side part of a laminated body. An operating part (13) moved to come into contact with or separate from the contact point of the switching circuit so as to perform the flashing operation of the light emitting body is provided on the upper or side part of the main body case. The portable flashlight can be reduced in size and, therefore, can be carried as if the flashlight is a key holder.
