A car window glass assembly comprising: a car window glass plate in which a conductor layer having a predetermined pattern is formed on a glass plate main surface; a connection terminal connected to the conductor layer via a pair of join portions formed of a first solder layer and a second solder layer each made of an indium-containing lead-free solder; and a power line fixed to the connection terminal, wherein the connection terminal includes: a first join part made from a metal plate, and joined to the conductor layer via the first solder layer; a second join part made from a metal plate, and joined to the conductor layer via the second solder layer; a bridge section made from a metal plate, and connected to the first join part and the second join part so as to be spaced apart from the conductor layer; and a fixing part for fixing the power line to a bridge section main surface of the bridge section, wherein the power line extends from the fixing part along the glass plate main surface, wherein a direction in which the power line extends is orthogonal to a virtual line connecting a center portion of the first join part with a center portion of the second join part, characterized in that a starting point of the power hne extending from the fixing part is located at a position in an upper direction of the virtual line, that the starting point is located at a position in an upper direction of a middle point of the virtual line, and that the upper direction of the middle point is a direction vertical to the glass plate main surface. a car window glass plate in which a conductor layer having a predetermined pattern is formed on a glass plate main surface; a connection terminal connected to the conductor layer via a pair of join portions formed of a first solder layer and a second solder layer each made of an indium-containing lead-free solder; and a power line fixed to the connection terminal, wherein the connection terminal includes: a first join part made from a metal plate, and joined to the conductor layer via the first solder layer; a second join part made from a metal plate, and joined to the conductor layer via the second solder layer; a bridge section made from a metal plate, and connected to the first join part and the second join part so as to be spaced apart from the conductor layer; and a fixing part for fixing the power line to a bridge section main surface of the bridge section, a first join part made from a metal plate, and joined to the conductor layer via the first solder layer; a second join part made from a metal plate, and joined to the conductor layer via the second solder layer; a bridge section made from a metal plate, and connected to the first join part and the second join part so as to be spaced apart from the conductor layer; and a fixing part for fixing the power line to a bridge section main surface of the bridge section, wherein the power line extends from the fixing part along the glass plate main surface, wherein a direction in which the power line extends is orthogonal to a virtual line connecting a center portion of the first join part with a center portion of the second join part, characterized in that a starting point of the power hne extending from the fixing part is located at a position in an upper direction of the virtual line, that the starting point is located at a position in an upper direction of a middle point of the virtual line, and that the upper direction of the middle point is a direction vertical to the glass plate main surface.
