PROBLEM TO BE SOLVED: To efficiently obtain timing synchronization between a transmitting device and a receiving device. SOLUTION: The transmitting device is the device to be introduced to the inner part of a subject, and includes: a vibration detecting part for detecting a vibration from the subject and generating a vibration signal; a data storage part for storing transmission data; a peak detecting part for detecting the peak of the vibration signal; a transmission timing determining part for determining the transmission timing of the transmission data, based on peak detection time; and a data transmitting part for transmitting the transmission data at the transmission timing via an antenna.
