PURPOSE:To realize narrow pitch mounting in connection structure between boards and the miniaturization of electronic equipment by reducing a connection area. CONSTITUTION:A conductor 53 on the upper surface of a first insulating board 50 and a conductor 63 of a second insulating board 60 are connected by an outer side connection terminal 72, and a conductor 55 on the lower surface of the first insulating board 50 and the conductor 63 of the second insulating board 60 are connected by an inner side connection terminal 74. Since the outer side and inner side connection terminals 72 and 74 are arranged respectively on a surface thereto an insulator 80 is faced, the arranging pitch of connection terminals can be narrowed, and also the arranging pitches of the conductors 53 and 55 of the first insulating board 50 and the conductor 63 of the second insulating board 60 can be made small. Following this, the area of the electrical connection part of the board can be reduced. |
