An image capture lens includes, in following order from an object side, a first lens made of glass which has a meniscus shape with a convex surface facing the object side and has positive refractive power, an aperture stop, a second lens made of glass which has a meniscus shape with a convex surface facing an image side and has negative refractive power, and a third lens made of resin which has a convex surface facing the object side and has positive refractive power. The image capture lens satisfies following conditional formulae (1) and (2): f2/f<-3.5, and (1) f3/f>3.5, (2) where f: focal length of the entire lens system; f2: focal length of the second lens; and f3: focal length of the third lens.
