[Problems to be solved by the device]

 For example, as devices and the like using such a card type substrate become higher in performance and the card type substrate itself is made higher in density, the number of wirings connected to the card type substrate also increases.

However, in the conventional connection structure as described above, for example, even if the width and interval of the connection electrodes of the card type substrate are reduced to increase the density to increase the number, there is a problem in accuracy. Naturally, there is a limit to the number of wires that can be connected. For this reason, for example, it is inevitable to use a method in which a connection pin or the like is provided in a protrusion other than the end portion of the card type substrate and a high density connector or the like is connected.

However, in such a method, as compared with the above-described method of forming an electrode on the end portion of the card-type substrate and inserting the electrode into the connector, the configuration of the card-type substrate and the device itself becomes complicated, and the number of manufacturing steps is increased. There is a problem that it becomes more expensive and expensive.

Therefore, according to the present invention, the number of connectable wires and the like is greatly increased, and the manufacturing is relatively easy, and the card-type board and the connector can be configured easily so that the card-type board and the connector can be easily configured. It is intended to provide a connection structure.

[0013]

[Means for Solving the Problems]

 In order to achieve such an object, in the connection structure of the card-type substrate and the connector according to the present invention, the connecting electrodes at the end of the card-type substrate to be inserted into the connector are formed in a plurality of stages in the insertion direction, and the connection electrodes are connected. It is characterized in that a plurality of connection terminals in the connector corresponding to the electrodes for use and connected to these electrodes are also arranged in parallel.

[0014]

[Action]

 With such a connection structure of the card-type substrate and the connector, even if the widths and intervals of the connection electrodes and the like are the same, if the number of steps formed in the insertion direction is two, double or three steps. In that case, the number of connecting wires can be tripled, and the manufacturing method and man-hours do not have to be increased so much.
