The first and second leads are placed adjoining to each other and constitute a first lead group, and the third and fourth leads are placed adjoining to each other and constitute a second lead group. The spacing between the first lead group and the fifth lead, the spacing between the second lead group and the fifth lead, and the spacing between the first lead group and the second lead group are larger than the spacing between the first lead and the second lead and the spacing between the third lead and the fourth lead.
