A structure of a tape of consecutive semiconductor elements is constructed so that each of N consecutive semiconductor elements from the nth element to the (n + N-1)th element has a characteristic within a predetermined characteristic deviation range, and also each of N consecutive elements from the (n + 1)th element to the (n + Nlth element has a characteristic within that characteristic deviation range. Thus, when assembling a circuit or device using N elements starting from an element at any desired position, e.g., when using N elements from the nth element to the (n + N-1)th element, if, for example, the nth element is defective because of an error in mounting or another problem, it is possible to assemble the circuit or device using the N elements from the (n + 1)th element to the (n + N)th element.
