After the discovery of MgB$_{2}$, 7 years have already passed, and a new higher-$T_{c}$ superconductor has now been desired. In this invited session, we review our present status (struggle?) to find higher-$T_{c}$ superconductors along the following lines. 1) 2-dimensional Cu-oxides having different crystal structures with CuO$_{2}$ planes, such as ladders, Lieb model Cu-oxide etc. 2) Metal superconductors including light elements (boron, carbon etc.), being suggested with MgB$_{2}$, diamond etc. Recently, we found a new superconductor boron doped SiC which belongs to the same category with boron doped diamond and Si etc. 3) We also present the superconducting properties of the clathrate-type silver oxides Ag$_{6}$O$_{8}$AgNO$_{3}$ ($T_{c}$=1.04K) and Ag$_{6}$O$_{8}$AgHF$_{2}$ ($T_{c}$=1.36K).
