1. A vehicle lamp comprising: a plurality of light emitting elements and a projection lens, the vehicle lamp being configured to form a horizontally-long light distribution pattern by emitting light from the plurality of light emitting elements to a lamp front via the projection lens, wherein
the plurality of light emitting elements is mounted on a common substrate in a state in which the light emitting elements are arranged in a left-right direction and light emitting surfaces thereof face the projection lens,
the substrate is arranged in a state of being inclined in the left-right direction with respect to a vertical plane perpendicular to a lamp front-back direction,
the plurality of light emitting elements includes a plurality of first light emitting elements located closer to a front end portion of the substrate and a plurality of second light emitting elements located closer to a back end portion of the substrate,
the projection lens is divided into a first lens region for controlling direct light from the plurality of first light emitting elements and a second lens region for controlling direct light from the plurality of second light emitting elements, and
the projection lens is configured such that a focal length of the second lens region is set to a value greater than a focal length of the first lens region.
