PROBLEM TO BE SOLVED: To provide a solid-state image sensing device conducting a color image sensing by a high color reproducibility while being capable of obtaining a distinct image even in a near infrared-ray image sensing. SOLUTION: A multilayer-film interference filter 106 consists of a red region R, a green region G and a blue region B, and a red light, a green light and a blue light are transmitted through the regions R, G and B respectively. The red region R represents a multilayer-film interference filter consisting of seven dielectric layers 201R to 207R and has a layer constitution holding spacer layers 204R and 206R byλ/4 multilayer films composed of other dielectric layers. The green regions G and the blue region B have the layer constitutions holding the spacer layers 204G and 204B by theλ/4 multilayer films composed of other dielectric layers respectively. The total value of the optical-film thicknesses of the spacer layers at every region differs from other regions in the green region G. Either total value is smaller than a quarter of the design central wavelength of theλ/4 multilayer films. COPYRIGHT: (C)2008,JPO&INPIT
