Provided is a flexible printed circuit board having excellent flexibility and a diffusely reflective white surface (white surface) which does not tend to undergo color change even when irradiated with light such as short-wavelength light, i.e., has high light deterioration resistance, and does not tend to undergo color change even when placed in a high-temperature environment, i.e., has excellent thermal deterioration resistance. The white reflective flexible printed circuit board includes a flexible printed circuit board and a surface constituted by a white reflective material layer. The white reflective material layer is composed of a resin composition containing a fluororesin and an inorganic white pigment. Lighting equipment includes the white reflective flexible printed circuit board and an LED mounted on the surface side constituted by the white reflective material layer of the white reflective flexible printed circuit board.

An object of the invention is to provide a communication apparatus capable of communicating by transmitting and receiving a protocol signal in accordance with a predetermined protocol, when receiving a DIS without receiving an ANSam signal, or not receiving a CM signal within a predetermined period after transmission of the ANSam signal. With a line connection established, when a calling station receives a DIS without receiving the ANSam signal, the calling station sends a DCS signal or an NSS and then executes the protocol according to Recommendation T.30. Further, with a line connection established, when a called station does not receive the CM signal within a predetermined time t1 after transmission of the ANSam signal, the called station sends the DIS with bit number 6 reset, and executes the protocol according to Recommendations T.30 in response to the DCS signal or NSS sent from the destination communication apparatus. Furthermore, the protocol according to Recommendations V.8 and V.34 are executed in response to the CM signal or a CI signal in placed of the DCS signal or the NSS.
