A
laser device includes a support, a first
heat sink, a plurality of
laser light sources attached to the support, and a plurality of electrodes bridged between the plurality of
laser light sources and the first
heat sink. Each of the plurality of
laser light sources is movable with respect to the support. Each of the plurality of electrodes is electrically connected to one of the plurality of
laser light sources at a first connection portion, and is thermally connected to the first
heat sink at a second connection portion. In each of the plurality of electrodes, an extension part between the first connection portion and the second connection portion has flexibility, and a length of the extension part is larger than a
linear distance between the first connection portion and the second connection portion.
