A thermally assisted magnetic head is formed by performing a head forming process, a mounting part forming process and a light source mounting process in that order. In the head forming process, a planned area is secured on a light source placing surface of a slider substrate, then a magnetic head part is formed on a head area other than the planned area and a spacer for securing a mounting space for the laser diode is formed on the planned area. In the mounting part forming process, a light source mounting part is formed by removing the spacer. In the light source mounting process, a laser diode is mounted on the light source mounting part formed by the mounting part forming step.

A layered chip package includes a main body, and wiring that includes a plurality of wires disposed on a side surface of the main body. The main body includes: a main part including first and second layer portions; and a plurality of first and second terminals that are disposed on the top and bottom surfaces of the main part, respectively, and are electrically connected to the plurality of wires. The first and second terminals are formed by using electrodes of the first and second layer portions. The layered chip package is manufactured by fabricating a layered substructure by stacking two substructures each of which includes an array of a plurality of preliminary layer portions, and then cutting the layered substructure. The layered substructure includes a plurality of preliminary wires that are disposed between two adjacent pre-separation main bodies and are to become the plurality of wires.

In a ceramic capacitor according to the present invention, the electrode strips of an internal electrode and the dielectric strips of a ceramic dielectric member are arranged perpendicularly to the surface of a substrate, and as such, the plurality of electrode strips and the plurality of dielectric strips are arranged alternately along a parallel direction relative to the substrate surface. That is, the electrode strips and the dielectric strips are multi-layered along a parallel direction relative to the substrate surface, thereby facilitating the realization of multi-layering in the ceramic capacitor by a known patterning technology.
