A portable device enabling a user to visually recognize tampering with internal components. The portable device is for performing wireless communication with a predetermined communication subject and includes a circuit board, on which an electronic component used to perform wireless communication is mounted, and a case for accommodating the circuit board. The case includes a first case part 13 and a second case part 14. The first case part has a non-transparent portion 13a; 121 that is non-transparent to visible light and a transparent portion 13b; 122 that is transparent to visible light, arranged adjacent to and outward from the non-transparent portion, and transmissible to laser light. The second case part is transparent to visible light and formed from a synthetic resin. The second case part absorbs laser light and is superimposed with the first case part in a state joined with the transparent portion. |
