Abstract: A connection component can be firmly secured to an adherend member, in a state where a conductive member is compressed, to prevent a bubble from remaining in a securing member. The connection component includes a metal terminal, the conductive member provided on one surface of the metal terminal and deformable by compression, the securing member bonded to one surface of the metal terminal, and an exhaust path provided in at least one of the metal terminal and the securing member. The exhaust path is connected to or provided in at least one of a first securing surface of the securing member that is bonded to the metal terminal, and a second securing surface that is opposite to the first securing surface. The exhaust path exhausts a bubble generated in at least one of the first securing surface and the second securing surface.

Abstract: An object is to solve problems associated with a stretchable wire member that includes, for example, a garment with stretchable wires formed thereon, that is, to solve the problems of wrinkles and undulations that often occur after the garment is stretched. A stretchable wire member includes a fabric; a base layer disposed on a surface of the fabric; a conductive layer disposed in part of the fabric, the conductive layer being on a surface of the base layer; and a protective layer covering the conductive layer. In the stretchable wire member, an elastic modulus E′3 of a multilayer body portion including the fabric, the base layer, and the protective layer ranges from 1 MPa to 6 MPa.

Abstract: Provided is a waterproof member that can prevent the waterproof member from being damaged during affixation and that can inhibit water from entering without causing air bubbles or the like to enter. A waterproof member sandwiched between a first member and a second member so as to seal between the first member and the second member includes a rigid base, a flexible contact member provided on a front surface of the rigid base, and an adhesive layer provided on a back surface of the rigid base. The front surface of the rigid base has a first region f which is a partial region of the front surface and in which the flexible contact member protrudes from a periphery thereof and a second region s that is a remaining region of the rigid base excluding the partial region and that is separated from the first region.
