In a semiconductor device 1, a substrate 3 carries the first semiconductor element 2a and the second semiconductor element 2b. The first semiconductor element 2a has a plurality of first pads 4a and a plurality of second pads 4b arrayed along two facing sides of a major surface. The second semiconductor element 2b has a plurality of third pads 4c along sides where the first pads 4a and the second pads 4b are arrayed, and a plurality of fourth pads 4d along sides where the first pads 4a and the second pads 4b are not arrayed. First wirings 8 electrically connect the plurality of third pads 4c to the plurality of fourth pads 4d on the major surface. A plurality of electrodes 5 is arrayed along all the circumferential sides of the major surface of the substrate 3. Second wirings 6a electrically connect the plurality of first pads 4a and the plurality of fourth pads 4d respectively to the plurality of electrodes 5. Third wirings 6b electrically connect the plurality of second pads 4b to the plurality of third pads 4c.
