<p>PROBLEM TO BE SOLVED: To provide an electric connector capable of reducing a connection load and of miniaturizing and thinning a device through it and to provide a connection structure using it. SOLUTION: This electric connector for electrically connecting a circuit board or the like 1 to a BGA 3 is composed of: an insulating base material 5 interlaid between the circuit board or the like 1 and the BGA 3; plural first and second through holes each drilled in the thickness direction of the base material 5; first connection pins 8 formed of a conductive high-polymer, inserted into and supported by the respective first through holes and abutting on connected electrodes 2 of the circuit board or the like 1 and solder balls 4 of the BGA 3; and second connection pins 9 formed of a conductive high-polymer, inserted into and supported by the respective second through holes and abutting on the connected electrodes 2 of the circuit board or the like 1 and the solder balls 4 of the BGA 3. The both end parts of the plural first connection pins 8 and second connection pins 9 each are projected from both surfaces of the base material 5, and the dimension of the upper end parts of the respective second connection pins 9 projected from one of the surfaces of the base material 5 is set larger than that of the upper end parts of the respective first connection pins 8.</p> |
