Semiconductor device having columnar electrode and method of manufacturing same

A semiconductor device comprising:

• a semiconductor element having a plurality of electrode pads;
• a plurality of columnar electrodes connected to said plurality of electrode pads;
• a resin layer covering said semiconductor element and said columnar electrodes and having a surface;
• outer terminals disposed on the surface of said resin layer in such a way as to be electrically connected to said columnar electrodes;
• and
• re-wiring conductor portions provided between said electrode pads of said semiconductor element and said columnar electrodes;
• wherein said resin layer is made of relatively soft resin which is spin-coated.
