Plural inlets 1 are formed by a separation into individual pieces, and these plural inlets are arranged to a tape-like carrier such that the long side of each of the plural inlets is along the longitudinal direction of the tape-like carrier, whereby cost can be reduced by rearranging the inlets to the cheap tape-like carrier. Further, the plural inlets formed by separating into individual pieces are rearranged onto the tape-like carrier, whereby the change of the arrangement pitch of the inlets so as to correspond to the size of a final product at a customer side can be facilitated, and days taken for the development for newly supplying the inlets can be shortened.
