PROBLEM TO BE SOLVED: To provide an electronic device, hardly causing positional shifting in connecting patterns to each other, which are periodically arrayed on two boards. SOLUTION: A first oriented segment and a second oriented segment intersecting each other are defined on the surface of a first board. A plurality of terminals each extending in the direction parallel to the second oriented segment and periodically arrayed in a first period in the direction parallel to the first oriented segment are formed on the surface of the first board. A first and second dummy patterns each extending in the direction parallel to the second oriented segment are disposed on the outside of the terminal disposed most outside directing the positive orientation of the first oriented segment in the first period taking over the periodicity of array of the terminals. The end of the first dummy pattern directing the positive orientation of the second oriented segment is moved backward in the negative orientation of the second oriented segment from the end directing the same direction of the second dummy pattern, and each of the terminals is extended beyond the position of the first end of the first dummy pattern directing the positive orientation of the second oriented segment.
