    • PROBLEM TO BE SOLVED: To reduce short circuit failures caused by a solder.SOLUTION: A semiconductor device comprises: a semiconductor element 10 which includes a plurality of electrode pads 11 arranged on one principal surface along an outer periphery of the semiconductor element in a rectangular frame shape and columnar electrode terminals 13 vertically arranged on respective electrode pads 11. Central axes L1 of respective electrode terminals 13 are formed at positions displaced from respective centers of the electrode pads 11 to the outside of the semiconductor element 10 along a direction orthogonal to an arrangement direction of the electrode pads 11. The semiconductor further comprises a wiring board 20 on which the semiconductor element 10 is mounted and a plurality of connection pads 22 corresponding to the electrode pads 11 of the semiconductor element 10 are formed. The center L2 of each connection pad 22 substantially coincides with the center of each electrode pad 11 of the semiconductor element 10. Each connection pad 22 is formed in a rectangular shape extending along a direction orthogonal to an arrangement direction of the connection pads 22, that is, along a direction orthogonal to the outer periphery of the semiconductor element 10. The electrode terminals 13 are electrically connected with the connection pads 22 by solders 30.
