A terminal accommodating body includes a terminal accommodating chamber for each coupling terminal capable of accommodating a coupling terminal capable of being electrically connected to a terminal of an electronic component, and a terminal holding portion that holds the coupling terminal. In all the terminal accommodating chambers, in a plurality of common accommodating chambers in which the coupling terminal and one terminal portion in a one plate-like bus bar having a plurality of terminal portions electrically connectable to the terminal of the electronic component are capable of being replaced and accommodated, and a partition wall between the adjacent common accommodating chambers has an inter-chamber inserting portion into which the coupling portion is inserted in an accommodated state of the terminal portion to the common accommodating chamber, in order to accommodate a coupling portion in the common accommodating chamber.
