<p><P>PROBLEM TO BE SOLVED: To provide a surface-mounted current-detecting resistor capable of providing an excellent resistance temperature coefficient (T. C. R), by reducing surplus resistance while keeping an excellent heat dissipation property, and to provide its manufacturing method. <P>SOLUTION: This surface mounted current-detecting resistor is provided with: a resistance layer 11 formed of a resistance alloy material; an insulation resin layer 12; a pair of plate body-like undersurface electrodes 13; an undersurface insulation resin material 14 connecting the pair of undersurface electrodes to each other; a pair of upper-surface electrodes 15 fixed to upper surfaces at both ends of the resistance layer; an upper-surface insulation resin material 16 connecting the pair of upper-surface electrodes to each other; and plated layers 18 connecting the upper-surface electrodes to the undersurface electrodes. The undersurface electrode 13 is divided into an inner electrode 13a and an outer electrode 13b along the longitudinal direction of the resistor through the undersurface insulation resin material; recessed parts 17 are formed on side surfaces of the resistance layer and the upper electrodes; and the inner electrodes and the outer electrodes are respectively connected to the upper-surface electrodes by the plated layers divided by the resistance layer and the upper-surface insulation resin material filled in the recessed parts of the side surfaces of the upper-surface electrodes. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
