A projection lens has first-lens-body including first incidence part located in an area facing first light source and emission part located on a side opposite to the first incidence part, and second-lens-body including second incidence part located in an area facing second light source and third incidence part located between the first incidence part and the second incidence part, and has structure in which the first-lens-body and the second-lens-body abut against each other while first boundary surfaces and second boundary surfaces are interposed between the first-lens-body and the second-lens-body, the first boundary surfaces being provided between the emission part and the third incidence part, and the second boundary surfaces extending from boundary-line with respect to the first boundary surface until the first incidence part and the third incidence part, and the first boundary surfaces and the second boundary surfaces are disposed at acute angle while having the boundary-line disposed therebetween.

Vehicle lamp

A projection lens has a first lens body including a first incidence section disposed at a side facing a first light source and an emitting section disposed at a side opposite to the first incidence section, and a second lens body including a second incidence section disposed at a side facing a second light source, a structure in which the first lens body and the second lens body abut against each other in between first boundary surfaces, which are provided between the emitting section and the second incidence section, and second boundary surfaces, which are provided between the first incidence section and the second incidence section from a boundary line with respect to the first boundary surfaces is provided, and the first boundary surfaces and the second boundary surfaces are disposed at an acute angle including the boundary line therebetween.

Lighting tool for vehicle

A projection lens has a first lens body including a first incidence section disposed at a side facing a first light source and a first emitting section disposed at a side opposite to the first incidence section, and a second lens body including a second incidence section disposed at a side facing a second light source and a second emitting section disposed at a side opposite to the second incidence section, a structure in which the first lens body and the second lens body abut against each other via an intermediate layer which is interposed between facing boundary surfaces of the first lens body and the second lens body is provided, and a refractive index of the intermediate layer is smaller than a refractive index of the first lens body.
