To provide an electronic component and a manufacturing method thereof which suppress the deterioration of appearance due to corrosion and discoloration of a display.SOLUTION: An electronic component includes a metal outer case 3, and a display 5 formed by a groove 51 is formed on the outer surface of the outer case 3. The outer case 3 is provided with a covering 33 that closes the opening of the groove 51. The covering 33 is, for example, an insulating coating layer 32 that covers the outer case 3, and the outer surface of the outer case 3 is irradiated with laser light by transmitting the insulating coating layer 32.SELECTED DRAWING: Figure 3 【課題】表示の腐食や変色による見栄え悪化を抑制した電子部品及び電子部品の製造方法を提供する。【解決手段】電子部品は金属製の外装ケース３を有しており、この外装ケース３の外表面には溝部５１で形作られる表示５が形成される。外装ケース３には、溝部５１の開口を塞ぐ被覆体３３が備えられる。被覆体３３は、例えば外装ケース３を被覆する絶縁コーティング層３２であり、この絶縁コーティング層３２を透過させて、外装ケース３の外表面にレーザ光を照射する。【選択図】図３
