  • Patent number: 11949090
    Abstract: A winding-start region that is closer to a winding-start side than a positive electrode core exposed part has positive electrode mixture unit amounts of a positive electrode inner mixture layer and a positive electrode outer mixture layer that are approximately uniform or increasing toward a winding-end side in the winding direction. A winding-start facing region has negative electrode mixture unit amounts of a negative electrode inner mixture layer and a negative electrode outer mixture layer that are approximately uniform or increasing toward the winding-end side. The positive electrode inner mixture layer and the positive electrode outer mixture layer each have a positive electrode mixture unit amount that differs at two or more locations, excluding the positive electrode core exposed part. The negative electrode inner mixture layer and the negative electrode outer mixture each have a fluctuating part where the negative electrode mixture unit amount fluctuates toward the winding-end side.

  • Publication number: 20170345981
    Abstract: The device is comprised of a backing board, a light-emitting element disposed on the backing board having a laminate structure in which a second semiconductor layer is disposed above a first semiconductor layer, a light-permeable board disposed over the light-emitting element, a first connecting electrode ranging from a first side face of the backing board to a first side face of the light-permeable board and electrically connected to the first semiconductor layer, and a second connecting electrode ranging from a second side face of the backing board to a second side face of the light-permeable board and electrically connected to the second semiconductor layer, wherein connection to the mounting board is established via a second side face of the first connecting electrode and the second connecting electrode, the second side being opposed to a first side face looking to the backing board and the light-permeable board.
