1. A vehicle lamp comprising: a light emitting element disposed to be directed to a front side of the lamp; and a light transmissive member disposed closer to the front side of the lamp than the light emitting element, the light transmissive member comprising a front surface formed into a flat plane or a paraboloidal plane having a concavely curved surface portion in a center thereof and a rear surface having a light entering area where light from the light emitting element is caused to enter and an annular area situated on an outer circumferential side of the light entering area, the annular area having a plurality of curved surfaces and having a reflecting film formed thereon, wherein the light emitting element and the light transmissive member are configured and arranged so that light which is emitted from the light emitting element and enters the light transmissive member is internally reflected on the front surface of the light transmissive member and is then internally reflected again on the rear surface of the light transmissive member for emission from the front surface of the light transmissive member to thereby form a first light distribution pattern having a cut-off line at an upper end portion thereof, and wherein the light transmissive member has a lens portion provided on one of the front surface or the rear surface of the light transmissive member and configured to cause part of the light which is emitted from the light emitting element and enters the light transmissive member to be emitted towards the front side of the lamp as direct emitted light that is upwardly oriented so as to form a second light distribution pattern in a position that is spaced upwardly away from the cut-off line.
