An oxide material having a langasite-type structure having a desired surface condition and a desired outer shape is obtained stably. By adding at least one selected from the group consisting of Ir, Pt, Au, and Rh to a raw material which is a composition used for producing a desired oxide material as an additive element, it is possible to control the wettability between a die portion at a bottom end of a crucible and a melt of the raw material, thereby implementing stable production of the oxide material while controlling the wetting and spread of the melt of the raw material leaked out through a hole of the crucible.

The object of the invention is to provide a method of forming an external electrode of an electronic component whereby the external electrode can be formed in a stable fashion. In order to achieve this object, a method of forming an external electrode according to the present invention includes: a step of forming an electrode portion 301a on a side face 30a of a chip 30 constituting an electronic component by applying a conductive paste 20 from a direction facing this side face 30a; a step of forming an electrode portion 301b on a side face 30b of the chip 30 facing the side face 30a by applying the conductive paste 20 from a direction facing this side face 30b; a step of forming an electrode portion 301c so as to connect the electrode portion 301a and electrode portion 301b on the bottom face of the chip 30 respectively adjacent to the side face 30a and the side face 30b; and a step of forming an external electrode 301 comprising the electrode portion 301a, electrode portion 301b and electrode portion 301c by drying this chip 30.

There are provided a ceramic electronic component and a method for producing the ceramic electronic component, where a ground electrode layer can be directly coated with lead-free solder without lowering reliabilities. Terminal electrode 3 is provided with a ground electrode layer 21 of Cu having been formed by firing, a solder layer 22 formed of a lead-free solder based on five elements of Sn—Ag—Cu—Ni—Ge, and a diffusion layer 23 having been formed by the diffusion of Ni between the ground electrode layer 21 and the solder layer 22. Because the diffusion layer 23 of Ni is formed between the ground electrode layer 21 and the solder layer 22, the diffusion layer 23, which functions as a barrier layer, suppresses the solder leach of Cu from the ground electrode layer 21. The diffusion layer 23 of Ni can also suppress the growth of fragile intermetallic compounds of Sn—Cu. Therefore, a decrease in the bonding strength between the ground electrode layer 21 and the solder layer 22 can be prevented.

A method of forming an external electrode of an electronic component involving: a paste preparation step, a removal step, an element preparation step, a contact step, and a formation step. A jig with a groove into which an element forming the electronic component can be inserted is prepared. A conductive paste is filled in the groove, and then removed, so as to leave the conductive paste along a first wall surface of the groove and remove the rest. Then, element immediately above the groove is located, and inserted into the groove and moved toward the first wall surface. Finally, the element is moved along the first wall surface and toward the aperture in a state in which the ridgeline of the element is kept in contact with the first wall surface, and moved away from the first wall surface so as to separate the ridgeline from the first wall surface.
