Provided are urethane resin particles for slush molding which make it possible that inconveniences based on the slip-down of a pigment, on the aggregation of particles of the pigment, and on other causes are removed although this coloring is coloring onto the resin particle surfaces. The present invention is urethane resin particles for slush mold which contain a urethane resin and an additive, wherein the particles have a shape factor SF1 of 101 to 200, a shape factor SF2 of 120 to 240, and a central particle diameter of 20 to 500 μm. It is preferred that the urethane resin has a concentration of urea groups of 0.5 to 10% by weight, a total of the concentration of urethane groups and that of the urea groups of 4 to 20% by weight, a melting point of 160 to 260° C. and a glass transition temperature of −65 to 0° C.

A method of producing a surface-mount inductor by encapsulating a coil with an encapsulation material containing a resin and a filler using a mold die assembly is provided. In the method, a tablet and a coil are used. The tablet is prepared by preforming the encapsulation material into a shape having a flat plate-shaped portion and a pillar-shaped convex portion on a peripheral thereof. The coil is a wound conductive wire having a cross-section of rectangular-shape. The coil is placed on the tablet to allow both ends of the coil to extend along an outer side surface of the pillar-shaped convex portion of the tablet. The coil and the encapsulation material are integrated together while clamping the both ends of the coil between an inner wall surface of the mold die assembly and the outer side surface of the pillar-shaped convex portion of the tablet, to form a molded body. External electrodes are formed on a surface of or around an outer periphery of the molded body in such a manner that the external electrodes are electrically connected to the both ends of the coil at least a portion of which is exposed to the surface of the molded body.

The invention is directed to a method of working a small recess portion. In the method, prior to press-forming small recess portions arrayed in a row by pressing a predetermined number of pieces of aligned male dies to a metal base plate, the metal base plate is previously formed with a highly rigid portion at a predetermined portion at a vicinity of an imaginary line extending in a row direction along end portions of predicted press portions to which the respective male dies are pressed.

A surface-mount inductor according to this invention comprises a coil formed by winding a rectangular conductive wire in an outward spiral pattern (so that opposite ends of the conductive wire become outermost periphery), a core made primarily of magnetic powders and binder, and an external electrode formed on one surface of the core. Further, the surface-mount inductor is characterized by encapsulating the coil in the core so that winding axis of the coil is parallel to the surface of the core on which the external electrode is formed.
