A radioactive ray detecting apparatus provides for reduction of the dead area or region where radioactive rays cannot be detected, even if disposing the radioactive ray detectors to be dense or crowded. The radioactive ray detecting apparatus satisfies the following relationships, when assuming that distance between semiconductor elements is 'XG1', while the distance from the semiconductor element of one of the radioactive ray detectors up to the semiconductor element of other radioactive ray detectors is 'XG2', and distance between the semiconductor elements alighted in a Y-direction is &#x201c;YG1&#x201d;, and a horizontal pitch of a predetermined pixel pitch to be used as the radioactive ray detector is &#x201c;a&#x201d; and a vertical pitch thereof is &#x201c;b&#x201d;, width of a surface of each of plural numbers of semiconductor elements is &#x201c;c&#x201d; and length thereof is &#x201c;d&#x201d;, respectively:&#x2212;(1+2)/21=2+(&#x2212;2)

A flexible flat optical cable includes two flexible base sheets, one or more optical fiber core wires arranged between the base sheets and each comprising at least an optical fiber, and an adhesive layer provided between the base sheets to bond the base sheets. A non-adhesive region is formed on a surface of the base sheets or the adhesive layer adjacent, in a thickness direction of the base sheets, to at least a portion of the optical fiber core wires for allowing a portion of the optical fiber core wires to move in a direction intersecting with an axial direction of the optical fiber core wires.
