The invention provides a small wide-angle pick-up lens which is composed of six optical lenses with excellent optical characteristics. The pick-up lens is sequentially configured with a first opticallens with negative refractive power, a second optical lens with positive refractive power, a third optical lens with the positive refractive power, a fourth optical lens with the negative refractive power, a fifth optical lens with the positive refractive power and a sixth optical lens with the negative refractive power from an object side, and specified conditional formulas are met.
