摘要： A light-emitting device includes a light-emitting element group comprised of a plurality of light-emitting elements (1-1,1-2,...,1-5), first drive device (80) for driving the plurality of light-emitting elements in succession, resistance section (6-1) connected to the light-emitting element group. The resistance section (6-1) is connected in common to the plurality of light-emitting elements (1-1,1-2,...,1-5). The light-emitting device further includes second drive device (8) for driving the light-emitting element group.

摘要： A recording head includes a light emitting element array (101) having a plurality of light emitting elements, a first substrate (100) on which the light emitting element array (101) is carried, a drive element (110) for driving the light emitting element array, a second substrate (103) on which the drive element (110) is carried, and a connecting member (102) for connecting the first substrate and the second substrate together. A wiring pattern formed on the first substrate (100) and an electrically conductive pattern on the connecting member are connected together by wire bonding (118).
