    摘要： This invention provides a composite magnetic sheet, which has excellent magnetic properties while realizing high strength and thickness reduction, and a process for producing the same. The composite magnetic sheet (1) comprises at least a resin (20) and a metallic magnetic powder (10). The metallic magnetic powder (10) comprises flat-shaped powder particles having a major axis and a minor axis. In the flat-shaped powder particles, the major axis is in the range of not less than 5 μm and not more than 80 μm, and the aspect ratio defined by the dimension ratio between the major axis and the minor axis is not less than 5 and not more than 20. In the composite magnetic sheet (1), the metallic magnetic powder (10) is dispersed so that the major axis is aligned parallel along the surface of the composite magnetic sheet (1).

    摘要： A terminal plate member (100) on which a terminal (32) of a coil component (30) is mounted comprises an annular frame (10) having an inner peripheral edge; a pair of extension members (15, 16) extending from the inner peripheral edge of the annular frame (10) toward an inner space of the annular frame member (10) in a first direction; and a throughhole section (18, 22) provided in the annular frame (10) at proximal end (15b, 16b) of one of the pair of extension members (15, 16). The throughhole section (18, 22) is provided along a second direction with a length bigger than the width of the one of the pair of extension members (15, 16), and the second direction is perpendicular to the first direction. A method of manufacturing an electronic component incorporating the terminal plate member is also described.
