PURPOSE: To provide a terminal part structure with which the connection work with a printed board and the space necessary for connection are remarkably lessened by composing the terminal part structure in which a terminal boards of an electric appliance are contained wherein the terminal boards have a screw hole at almost the same height as that of the upper face of a cubic main body case and are arranged in parallel to the case side faces while their sides to be connected with outer conductors being kept horizontally.

CONSTITUTION: Space 1e into which a compression spring can be inserted in compressed state is formed in the lower face side of a terminal board 5 by the terminal board 5 and a main body case 1 and at the same time a slit 1a is formed in the case side face 1d to make a thin rod able to be led to the case lower face side from the space 1e. A thin rod is united with a spring main body to be inserted into the space 1e, so that, together with the spring main body, it can compose a connection conductor.
