A microphone substrate 37 is provided behind the microphone 35.

In this embodiment, since the exterior of the guide tube 3 is generally made of a light heat-shrinkable tube 91, the weight of the guide tube 3 can be reduced. Suction tube 31
Since the microphone 35 is installed behind the front end opening 92, the space for installing the front end member 6 can be made more efficient. Since a plurality of, for example, three microphone holes 36 provided on the front surface of the microphone 35 are provided, even if water is applied to these portions, it is difficult for the microphone 35 to enter the front surface of the microphone 35, and even if water enters, it easily flows out. be able to. Also, the function of the microphone 35 can be secured through any one of the microphone holes 36 without blocking all the microphone holes 36 with water, dust, or the like.

It should be noted that the present invention is not limited to the above-described one, and various modifications are conceivable.
For example, a treatment channel that opens at the distal end of the guide tube may be provided so that a treatment tool such as forceps can be inserted from the hand side. In the above embodiment, the functions of detecting gas, temperature, and the like are provided on the guide tube side, but these may be incorporated in the endoscope itself.

For example, the configuration may be such that a tube is simply attached to the outer periphery of the insertion section of the endoscope. Further, by using a tube made of a relatively hard material, the same protection function as that provided with the exterior can be obtained. When the outer member is omitted, the tube can be easily replaced when the tube is clogged or needs to be replaced. Further, the guide tube can be provided economically. <Supplementary notes> In an endoscope device for disaster countermeasures that performs a search operation using an endoscope, a gas detection device installed near the tip of the insertion section side of the endoscope device guided into the search target area for gas detection Disaster countermeasures, characterized in that a sampling opening is provided, and a gas guide tube for connecting the sampling opening to a detection port of a gas detection device installed on the operation unit side of the endoscope apparatus is provided.
