Abstract: PROBLEM TO BE SOLVED: To provide a thin and small semiconductor device and improve the adhesion of a seal resin thereof to a resin board. SOLUTION: Lead electrodes 33 are formed on the front surface of a resin board 31 on which an IC chip 35 connected to the electrodes 33 is mounted. The electrodes 33 are electrically connected to lead electrodes 32 at the back side through through-hole electrodes 34 piercing the board 31. A resin 36 for sealing the top and side faces of the board 31 involving the IC chip 35 is charged in the through-hole electrodes 34 from the top face of the resin board 31 to enhance the adhesion of the resin 36 to the board 31. Contact electrodes 32a are connected through the lead electrodes 32 to the through-hole electrodes 34 and solder electrodes are formed apart from the through-hole electrodes 34. Thus it is possible to improve the connection reliability for mounting on the circuit board, without flowing a molten solder into the through-hole electrodes 34 at reflowing.
