  "textContent": "In a vehicle lamp configured to emit light from a plurality of light emitting elements to a lamp front via a projection lens, a horizontally-long light distribution pattern can be formed as a clear light distribution pattern even in a case where a substrate is inclined in a left-right direction with respect to a vertical plane perpendicular to a lamp front-back direction. A projection lens (40) is divided into a first lens region (40A) for controlling direct light from six first light emitting elements (30A) located closer to a front end portion of a substrate (50) and a second lens region (40B) for controlling direct light from six second light emitting elements (30B) located closer to a back end portion of the substrate (50), and a focal length of the second lens region (40B) is set to a value greater than a focal length of the first lens region (40A). With this configuration, the six first light emitting elements (30A) and the six second light emitting elements (30B) can be arranged in an appropriate positional relationship with respect to a back focal point (F 1) of the first lens region (40A) and a back focal point (F2) of the second lens region (40B).",
