Since the gas-liquid detection sensor is constructed using the same cable, there is no need to connect the lead wire to the element, and the sensor can be manufactured in the same way as a flat cable.

出するよう挟着して気液検知センサｌを構成する。The present invention will be explained based on FIGS. 1 and 2. One resin tape 2 made of polytetrafluoroethylene resin (PTFE) is provided with openings 3, and a resin tape 2 is provided along the longitudinal direction of this tape 2. It was formed by mixing two pairs of conductors 5 made of silver-plated mild steel and carbon fibers that bridge these conductors 5 at the positions of the openings 3 of one of the resin tapes 2 in 1) 'l'' F E. The conductive resin body 6 and the other resin tape 4 made of PTFE which sandwich the conductor 5 and the resin body 6 between the one resin tape 2 are exposed through the opening 3. A gas-liquid detection sensor 1 is constructed by sandwiching them in this way.

ットケーブルと同じ工程を使える。In order to adopt such a configuration, during manufacturing, the resin tape 4 and the conductor 5 are continuously fed out from a roll, the conductive resin 6 is provided at a predetermined interval, and the resin tape 2 is provided with holes 3 at the same intervals. You can use the same process as for flat cables, which involves continuously supplying and integrating them.

。The flat cable-shaped sensor group manufactured in this way can be put into practical use simply by cutting off the required parts and peeling off the insulating tape at the ends. This eliminates the need to connect wires and improves productivity. Furthermore, since the connecting portion between the conductor and the conductive resin body is protected with a resin tape, molding with epoxy or the like is not required, and the sensor can be made thinner and smaller.

The conductive resin body is composed of a conductive resin body for gas-liquid sensing that is bridged at the position, and another resin tape that holds these conductors and the conductive resin body between the one resin tape, and the conductive resin body Since one resin tape and the other resin tape are sandwiched so as to be exposed through the perforation to form a gas-liquid detection sensor, it can be produced continuously in the same way as a flat cable. And since it can be put into actual use simply by cutting off the required parts and peeling off the insulating tape at the ends, there is no need to connect the conductive resin body that is the element part and the lead wires, which is required in the past, improving productivity. At the same time, it is possible to reduce costs.
