A solid name plate with an air chamber is provided to remove contaminants on the name plate from an outside contamination source by forming intaglio and relief patterns engraved on the name plate inside upper and lower plates. A solid name plate includes a print surface, a bond surface(50), and an air chamber(30). The print surface forms insides of an upper plate(10) and a lower plate(20) of the name plate as an intaglio or a relief. The bond surface maintains airtightness when bonding the upper and lower plates. The air chamber is formed between the upper and lower plates by bonding the bond surface. An inlet of the air chamber is formed on a side of the name plate to inject liquid or gas.
