The light source unit (10) includes a lens array (23) including a plurality oftwo-dimensionally disposed lenses (25) and a lens substrate portion (26) that supports the plurality of lenses (25), and an element substrate portion (22) that supports a plurality of light emitters (21). The element substrate portion (22) has a second coefficient of liner expansion. The first coefficient of linear expansion is approximately same as the second coefficient of linear expansion of the element substrate portion (22). The light source module (100) includes the light source unit (10), and a condenser lens (20, 33, 50) configured to collect and condense pump light emitted from the light source unit (10). The laser ignition device (100) includes the light source module (100), and a laser resonator (40) configured to absorb the pump light emitted from the light source unit (10).",
