PROBLEM TO BE SOLVED: To provide a freely stackable circuit unit applicable to materials other than an electric wire in constituting a wiring pattern, which is positioned easily and provides wide flexibility for the wiring pattern. SOLUTION: A plurality of conductors 2 are arranged parallel in an insulated and coated layer 3, a plural sets of holes 4, which are formed avoiding the conductors and at least one of which is treated as a set, are arranged along the longitudinal direction of the conductors on the layer 3, and a plurality of projections 5 which can be fitted to a hole 4B corresponding to a hole 4A are arrayed at the distance equal to a set in the longitudinal direction of the conductors on the one surface 3a of the layer 3. The holes 4 and projections 5 are each arrayed on the same straight line and arrayed symmetrically at both sides of the layer 3. When the number of hole 4 of a set is plural, the projections 5 are arrayed at a fixed distance D. A hole 4A which neighbors a projection 5 is arranged at a certain interval (p) within the certain distance D. |
