A surface of the main body portion of one of the bus bars is opposed to a surface of the main body portion of the other one of the bus bars, and the other bus bar and the one bus bar are arranged one after the other in a direction perpendicular to the surface of the main body portion. The connection terminal portions of the one bus bar, the connection terminal portions of the other bus bar arc arranged one after the other in a direction along the surface of the main body portion. ## Claims ### Claim 1 A connection member comprising a primary bus bar and a secondary bus bar, each of which includes a main body portion and a connection terminal portion while the connection terminal portion is formed at the main body portion and serves as a portion to be connected to a corresponding component-side terminal portion of an electric component, wherein: in a state where the primary bus bar and the secondary bus bar are arranged one after another in a perpendicular direction that is perpendicular to a surface of the main body portion of each of the primary bus bar and the secondary bus bar, the connection terminal portion of the primary bus bar and the connection terminal portion of the secondary bus bar are arranged one after another in a crossing direction that crosses the perpendicular direction. ### Claim 2 (depends on 1) The connection member according to claim 1, wherein the connection terminal portion of the primary bus bar and the connection terminal portion of the secondary bus bar are arranged one after another in a direction that is along the surface of the main body portion. ### Claim 3 (depends on 2) The connection member according to claim 2, wherein each of the connection terminal portion of the primary bus bar and the connection terminal portion of the secondary bus bar has a connection surface that extends along the surface of the main body portion and is to be connected with the corresponding component-side terminal portion. ### Claim 4 (depends on 1) The connection member according to claim 1, wherein each of the connection terminal portion of the primary bus bar and the connection terminal portion of the secondary bus bar has a connection surface that extends in the crossing direction and is to be connected with the corresponding component-side terminal portion. ### Claim 5 (depends on 2) The connection member according to claim 2, wherein each of the connection terminal portion of the primary bus bar and the connection terminal portion of the secondary bus bar is placed at a position that coincides with a position of the primary bus bar or a position of the secondary bus bar in the perpendicular direction. ### Claim 6 (depends on 1) The connection member according to claim 1, wherein the connection terminal portion of the primary bus bar and the connection terminal portion of the secondary bus bar are placed between the primary bus bar or the secondary bus bar in the perpendicular direction. ### Claim 7 (depends on 1) The connection member according to claim 1, wherein the connection terminal portion of the primary bus bar and the connection terminal portion of the secondary bus bar are placed between two opposite outermost bus bars among a plurality of bus bars that include the primary bus bar and the secondary bus bar and are arranged one after another in the perpendicular direction. ### Claim 8 (depends on 1) The connection member according to claim 1, wherein: the primary bus bar includes an electric current terminal portion, through which an electric current is inputted or outputted to the main body portion of the primary bus bar; the secondary bus bar includes an electric current terminal portion, through which the electric current is inputted or outputted to the main body portion of the secondary bus bar; the main body portion of the primary bus bar and the main body portion of the secondary bus bar are arranged one after another and are spaced from each other in a plate thickness direction of each of the main body portion of the primary bus bar and the main body portion of the secondary bus bar; and the electric current terminal portion of the primary bus bar and the electric current terminal portion of the secondary bus bar project in a common direction at a corresponding position of the main body portion of the primary bus bar and a corresponding position of the main body portion of the secondary bus bar, respectively, which are displaced from each other in an extending direction of each of the main body portion of the primary bus bar and the main body portion of the secondary bus bar. ### Claim 9 (depends on 1) An electric component unit comprising: the connection member of claim 1; and a plurality of the electric components, each of which includes the component-side terminal portion connected to the corresponding connection terminal portion. ### Claim 10 (depends on 9) The electric component unit according to claim 9, comprising a bus bar receiving case that receives the primary bus bar and the secondary bus bar such that the primary bus bar and the secondary bus bar are arranged one after another in the perpendicular direction that is perpendicular to the surface of the main body portion of each of the primary bus bar and the secondary bus bar. ### Claim 11 (depends on 9) A battery device comprising: the electric component unit of claim 9; and a secondary battery.
