PROBLEM TO BE SOLVED: To provide a security wireless communication method and a high security wireless communication apparatus enhancing the secrecy while maintaining a normal communication state. SOLUTION: Each of first and second wireless communication apparatuses is provided with: a high sensitivity reception mode transition request means for making a request of transition to a high sensitivity reception mode to a data receiver side at data transmission when a communication link is established between both of them (step S3); a high sensitivity reception mode transition means which transitions to the high sensitivity reception mode when receiving, at data reception, a transition request to the high sensitivity mode from the high sensitivity reception mode transition request means of the data transmission side (step S26); and a low transmission power mode transition means transitioning to a low transmission power mode to transmit transmission data when receiving, at data transmission, a transition notice to the high sensitivity reception mode from the high sensitivity reception mode transition means at a data receiver side (step S5).
