This study conducted analysis of paint samples from a streetcar No. 381 (Registration Cultural Property No. 467) to identify the characteristics of the modern paint. The samples were analyzed by Microscopic observation, infrared spectroscopy and SEM-EDS. The upper part is consist of 26 layers and the under part is 29 layers. And the layers were painted various thickness from $10{\mu}m$ to $100{\mu}m$, and confirmed that several color had been used. The putty was used for surface treatment before painting. According to the results of infrared spectroscopy, paint specimens were identified as alkyd resin. Some bands such as C-H and C=O stretcing, aromatic, C-H bending, C-O stretching were found in spectra. Inorganic analysis showed that gold color on the surface was used copper-based paint. And type of the putty was lacquer-putty that was consist of kaolin, talc and zinc white.
