A terminal connection component including press-fit terminals and terminal metal-fittings. The press-fit terminals have a plate shape in which a taper is disposed at one tip, and the terminal metal-fittings also have a plate shape in which a fitting section is disposed at one end side. The fitting sections of the terminal metal-fittings have a first hole part and a second hole part from the one end in parallel. The tips of the press-fit terminals are press-fitted and are connected to the fitting sections of the terminal metal-fittings, and a portion between the first hole part and the second hole part of the fitting section, which serves as an elastic deformation section, is elastically deformed in a thickness direction of the press-fit terminal and biases the press-fit terminal so that the press-fit terminals are surely press-fitted to the fitting sections of the terminal metal-fittings.
