1. A semiconductor light emitting device, comprising:

  • a light emitting unit includinga semiconductor stacked body including a firstsemiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type, and a light emitting layer provided between the first semiconductor layer and the second semiconductor layer, the semiconductor stacked body having a first major surface on a first semiconductor layer side and a second major surface on a second semiconductor layer side,a first electrode electrically connected to the first semiconductor layer on a second major surface side, anda second electrode electrically connected to the second semiconductor layer on the second major surface side;

    a first conductive member electrically connected to the first electrode, the first conductive member including a first columnar portion provided on the second major surface to cover a portion of the second semiconductor layer on the second major surface side, the first columnar portion being separate from the second semiconductor layer;

    an insulating layer provided between the first columnar portion and the portion of the second semiconductor layer on the second major surface side;

    a second conductive member electrically connected to the second electrode, the second conductive member including a second columnar portion provided on the second major surface;

    a sealing member covering a side surface of the first conductive member and a side surface of the second conductive member; and

    an optical layer provided on the first major surface of the semiconductor stacked body, the optical layer including a wavelength conversion unit configured to absorb an emitted light emitted from the light emitting layer and emit light having a wavelength different from a wavelength of the emitted light;

    wherein the first conductive member further includes a first connection portion covering at least a portion of the insulating layer to electrically connect the first electrode to the first columnar portion.
