There is a problem that when a silver powder sintering paste that is substantially free from resin is used, an organic solvent used as a dispersion medium bleeds, which results in contamination and wire bonding defects. In order to solve the problem, provided is a metal powder sintering paste that contains, as a principal component, silver particles having an average particle diameter (a median diameter) of 0.3 μm to 5 μm and further contains an anionic surfactant but is substantially free from resin.

The present invention discloses a method for producing a component containing copper by selective laser sintering, comprising the following method steps: —providing (S1) a metal power containing a copper-chromium alloy; —selectively melting (S2) the metal powder by laser radiation to produce the component; —heating (S3) the component to a temperature in the temperature range between 900° C. and 1000° C. in an oxygen-containing atmosphere; and —removing (S4) a chromium oxide layer formed on the surface of the component.

A coil component includes: a magnetic body part and a cover part covering one side of a magnetic layer part; and a coil part embedded in the magnetic body part. The magnetic body part is comprised of the following two types of layers: (A) an oblate soft magnetic grain-containing layer, and (B) a spherical grain-containing layer, wherein layer (A) extends over the entire range of the magnetic body part except for a portion including the coil part in a direction perpendicular to an axis direction of the coil part, layer (B) adjoins layer (A) in the axis direction. The cover part is constituted by multiple layers including one or more of layer(s) (A) and one or more of layer(s) (B) and extending over the entire range of the magnetic body part in the direction perpendicular to the axis direction.
