A mounting structure for mounting a terminal at a circuit board, which allows the terminal to be mounted at the circuit board easily by using an automatic mounter and facilitates inspection of the bonding state at the mounting area where the terminal is mounted at another board, is provided. The mounting structure for a circuit board terminal also assures a sufficient level of strength at the terminal mounting area, reduces the electrical resistance and improves the usable area ratio at the circuit board. According to the present invention, one or a plurality of recessed electrodes ( 1 a) are formed at an end of a circuit board ( 1 ) in correspondence to each terminal. One or a plurality of hollow through electrodes ( 1 b) are disposed near the recessed electrodes ( 1 a) at the circuit board ( 1 ) in correspondence to each terminal. A mounting portion ( 4 b) of each terminal ( 4 ) which is mounted at the circuit board ( 1 ), includes a first vertical portion ( 4 c), a horizontal portion ( 4 d) and a second vertical portion ( 4 e) formed by bending the front end of the horizontal portion ( 4 d). The first vertical portion ( 4 c) is fitted at the recessed electrodes ( 1 a) at the circuit board ( 1 ) and is then bonded to the circuit board ( 1 ) via a conductive bonding material. The second vertical portion ( 4 e) is inserted at the through electrodes ( 1 b) and is then bonded via a conductive bonding material.
