Liquid surface detection apparatus and manufacturing method of same

A liquid surface detection apparatus for sensing a liquid surface level of liquid stored in a container, comprising:

• a float that floats on the liquid;
• a sensor element that senses a position of the float;
• a terminal that is made of an electrically conductive material, wherein a lead line, which outputs a measurement signal of the sensor element to an outside, is connected to the terminal;
• and
• a body that is formed integrally with the terminal and includes a dielectric portion, which is made of a dielectric material, wherein:
• the terminal includes:
• a connecting portion that is provided in a connecting area of the terminal, which is exposed from the body;
• a bent portion that is continuous with the connecting area, wherein the bent portion is bent on a bending side where the connecting area is exposed, so that the lead line is connected between the bent portion and the connecting portion;
• and
• a projecting wall portion that is formed continuously with the connecting area together with a side of a base of the bent portion, wherein the projecting wall portion projects in a form of a standing wall from the connecting area;
• and
• the body includes an extending portion that is securely joined to:
• a fixing part of a side surface of the bent portion located on a counter-bending side of the bent portion that is opposite from the bending side of the bent portion;
• and
• a fixing part of the projecting wall portion;
• and
• the extending portion extends from the fixing part of the side surface of the bent portion and the fixing part of the projecting wall portion toward a side that is opposite from the connecting portion.
