摘要： An image capturing lens is disclosed, which is compact and capable of capturing an image at a wide angle though realizing low cost performance by enabling mass productions of wafer-scale lenses, and an image capturing device is disclosed, which uses this image capturing lens. For the purpose of attaining short focusing, a wide angle of view can be ensured by optimally disposing the power of a first lens block and the power of a second lens block so that a value of a conditional formula (1) becomes higher than a lower limit. Hereat, a wider angle can be attained by strengthening the positive power of the second lens block against the first lens block without increasing the overall length. While on the other hand, the value of the conditional formula (1) becomes lower than an upper limit, whereby the power of the second lens block is prevented from being excessively strengthened, the lens units of the second lens block can be configured with a small sag quantity, and moldability can be kept preferable, 0.9
