PROBLEM TO BE SOLVED: To provide a photographing lens device equipped with a photographing lens system whose exit pupil is positioned nearly at infinity and whose entire length is short. SOLUTION: The photographing lens device is equipped with the photographing lens system and a solid-state image pickup element where plural photodetectors receiving image light emitted from the photographing lens system are arrayed in order from an object side. The photographing lens system is constituted of a 1st group having negative refractive power as a whole and consisting of two lenses including a lens provided nearest to the object side and having negative refractive power, a 2nd group having positive refractive power and a 3rd group consisting of one lens having positive refractive power in order from the object side. The photographing lens system is a zoom lens system, and variable power is performed by fixing the 3rd group and moving the 1st and the 2nd groups.
