To provide a board connection structure which is easy to be assembled and can connect connectors appropriately.SOLUTION: A connection structure between boards includes a first board provided with a first connector, a second board provided with a second connector coupled to the first connector, a protrusion protruding along a direction in which the first connector and the second connector are coupled from the first board, and a guide hole provided in the second board and into which the protrusion is fitted. In the projection, the insertion length of the projection from a fitting portion with the projection in the guide hole is set to be larger than the fitting length between the first connector and the second connector.SELECTED DRAWING: Figure 7A【課題】組み立てが容易であり、コネクタ同士を適切に接続できる基板同士の連結構造を提供すること。【解決手段】基板の連結構造は、第１コネクタが設けられた第１基板と、前記第１コネクタと連結される第２コネクタが設けられた第２基板と、前記第１基板から前記第１コネクタと前記第２コネクタとが連結される方向に沿って突出する突起と、前記第２基板に設けられ、前記突起が嵌合するガイド孔と、を備える。前記突起において、前記ガイド孔における前記突起との嵌合部からの前記突起の挿入長は、前記第１コネクタと前記第２コネクタとの嵌合長よりも大きく設定されている。【選択図】図７Ａ
