PROBLEM TO BE SOLVED: To solve the problem that a timepiece for mounting an infrared communication module is required to get large, since a shielding member is required to be provided in the infrared communication module itself because the module is weak against a noise, and since a size of the module gets large thereby. SOLUTION: A shielding pattern 4a is provided in a circuit board 4 for mounting the infrared communication module 1, the module 1 is mounted on the shielding pattern 4a, and shielding against the noise is allowed thereby without using the shielding member. |
