To provide a method of manufacturing a low heat-resistant sensor that has high chemical resistance, excellent drip-proof properties, and excellent dust-proof properties. A method of manufacturing a low heat-resistant sensor includes a step of disposing a sensor unit in a recessed portion of a container composed of fluorine resin, inserting a cable into a through-hole in communication with the recessed portion, and electrically connecting the sensor unit that is disposed in the recessed portion and the cable to each other, a step of disposing a plate composed of fluorine resin such that the plate covers an opening of the recessed portion and capping the recessed portion, a step of covering the cable by using a tube composed of fluorine resin, a step of disposing a frame body composed of fluorine resin such that the frame body surrounds a perimeter of the plate, a step of thermally bonding the frame body, the container, and the plate to each other, and a step of thermally bonding the container and the tube to each other.

Method of manufacturing low heat-resistant sensor

A low heat-resistant sensor that has high chemical resistance, excellent drip-proof properties, and excellent dust-proof properties is provided. The low heat-resistant sensor includes a sensor body that includes a sensor unit that is disposed in a housing and a cable that is electrically connected to the sensor unit of the sensor body. The housing of the sensor body is composed of fluorine resin, the cable is covered by a tube composed of fluorine resin, a portion at which the housing and the tube are connected to each other is thermally bonded, and the housing and the tube are integrally formed.

Low heat-resistant sensor

A substrate with a conductive layer including a substrate, which is a woven or nonwoven fabric containing polytetrafluoroethylene (PTFE) nanofibers; and a conductive layer formed on the substrate, the conductive layer being formed from a conductive composition with a viscosity in a range of 1 to 500 Pa&#xb7;s measured at 25&#xb0; C. with a rotational viscometer at a rotational speed of 50 rpm, wherein the following requirement (1) is satisfied: requirement (1); the substrate with a conductive layer has a Gurley permeability of 10 s/100 ml or less.

Substrate with conductive layer

A piezoelectric stack includes a porous resin sheet, and a surface coating layer disposed on an exterior surface of the porous resin sheet, the exterior surface including at least one of a front surface and a back surface of the porous resin sheet, the surface coating layer having a volume resistivity of not less than 1&#xd7;10&#x3a9;&#xb7;cm, the porous resin sheet and the surface coating layer having different elastic moduli.
