Abstract: Provided is a sensor sheet, a capacitive sensor, and a method for manufacturing sensor sheet with which it is possible to suppress changes in capacitance due to an arrangement state. This sensor sheet (1) includes a pair of electrode layers (1X-4X, 1Y-4Y), constraint layers (32, 42) that regulate the surface-direction expansion and contraction of the electrode layers (1X-4X, 1Y-4Y), a plurality of detection parts (A (1, 1)-A (4, 4)) disposed in portions where the pair of electrode layers (1X-4X, 1Y-4Y) is overlapped when viewed from the lamination direction, and non-detection parts (G) disposed between the plurality of detection parts (A (1, 1)-A (4, 4)). In a no-load state, the constraint layers (32, 42) are disposed in at least some of the plurality of detection parts (A (1, 1)-A (4, 4)), and gaps (g) are partitioned in at least some of the non-detection parts (G).

Abstract: A sensor sheet and a capacitance-type sensor are provided in which the proportion of a dead area to the entire sensor body is small and detection units that are incapable of detection do not tend to be formed after being cut. A sensor sheet includes a pressure sensing area in which a plurality of detection units are set, and a dead area that is disposed adjacent to the pressure sensing area in a planar direction and that has a take-out portion. A front-side detection path that passes by way of front-side jumper wiring layers and a back-side detection path that passes by way of back-side jumper wiring layers are set between the detection units and the take-out portion. The sensor sheet is cuttable while securing a sensor body that has at least one detection unit, the take-out portion, and the front-side detection path and the back-side detection path for the detection unit.

Abstract: A rear conversion lens system to be used for varying the focal length being inserted to the space between an objective for a single-lens reflex camera and film surface, the rear conversion lens system comprising a first lens component arranged as a positive lens, a second lens component arranged as a negative lens, a third lens component arranged as a positive meniscus lens, a fourth lens component arranged as a biconcave lens, and a fifth lens component arranged as a positive cemented doublet, the rear conversion lens system being arranged that the magnification is higher than 1.6 and aberrations are corrected favorably.
