A vehicle lamp comprising: a light source (14, 14') having a light emitting-surface (14a, 14'A); a first lens configured to deflect a first part of direct light from the light source (14, 14') to form a first light distribution pattern having a horizontal and oblique cutoff lines (CL1, CL2) on an upper side of the first light distribution pattern; and a second lens configured to horizontally diffuse a second part of the direct light from the light source (14, 14') to form a second light distribution pattern (PB1, PB2) that overlaps the first light distribution pattern, wherein the first lens is a convex lens, and is disposed on an optical axis (Ax) extending in a front-rear direction of the vehicle lamp, the light source (14, 14') is arranged such that the light emitting-surface (14a, 14'A) faces forward in the front-rear direction, and such that a bottom side (14a1, 14'A1) of the light emitting-surface (14a, 14'A) is disposed on a plane including the optical axis (Ax) and has an end point located at a rear focal point of the first lens, and the first lens and the second lens are formed as a single unitary piece such that the second lens extends around the first lens, characterized in that the first lens and the second lens have substantially the same maximum thickness in the front-rear direction, the second lens has a shape of a portion of a convex lens other than a central portion of the convex lens, and the second lens is configured such that an upper portion of the second part of the direct light that is output from an upper portion (22a1) of the second lens above the optical axis (Ax) is diffused less in then vertical direction and is more concentrated near the optical axis (Ax) than a lower portion of the second part of the direct light that is output from a lower portion (22a2) of the second lens below the optical axis (Ax). a light source (14, 14') having a light emitting-surface (14a, 14'A); a first lens configured to deflect a first part of direct light from the light source (14, 14') to form a first light distribution pattern having a horizontal and oblique cutoff lines (CL1, CL2) on an upper side of the first light distribution pattern; and a second lens configured to horizontally diffuse a second part of the direct light from the light source (14, 14') to form a second light distribution pattern (PB1, PB2) that overlaps the first light distribution pattern, wherein the first lens is a convex lens, and is disposed on an optical axis (Ax) extending in a front-rear direction of the vehicle lamp, the light source (14, 14') is arranged such that the light emitting-surface (14a, 14'A) faces forward in the front-rear direction, and such that a bottom side (14a1, 14'A1) of the light emitting-surface (14a, 14'A) is disposed on a plane including the optical axis (Ax) and has an end point located at a rear focal point of the first lens, and the first lens and the second lens are formed as a single unitary piece such that the second lens extends around the first lens, the second lens has a shape of a portion of a convex lens other than a central portion of the convex lens, and the second lens is configured such that an upper portion of the second part of the direct light that is output from an upper portion (22a1) of the second lens above the optical axis (Ax) is diffused less in then vertical direction and is more concentrated near the optical axis (Ax) than a lower portion of the second part of the direct light that is output from a lower portion (22a2) of the second lens below the optical axis (Ax).
