Abstract

Sample plate (20) for laser desorption ionization is obtained by superimposing Al2O3 layer (22) having a multiplicity of pores (23) of about 20 to 30 nm diameter as a heat insulation layer on Al plate substratum (21) and superimposing on the surface thereof bilayer metal thin film (24) composed of Ti layer (24a) and Pt layer (24b). As the combination of dissimilar metals Ti/Pt exerts high H+ addition catalyzing capability, high ionization efficiency can be attained even when pores (23) of large diameter as in the prior art are not provided. Accordingly, the duration of anodizing treatment at the forming of the Al2O3 layer (22) can be short, and no special treatment for forming of the pores (23) of large diameter is needed. Therefore, the production can be facilitated, and the cost can be reduced.
