A heat spreading member is received on a predetermined surface of an electronic component. The heat spreading member extends larger than the predetermined surface. A contact piece is contacted with the heat spreading member over a contact area smaller than the predetermined surface. The contact piece serves to realize concentration of an urging force applied to the heat spreading member. The heat spreading member is thus reliably urged against the electronic component. The concentration of the urging force serves to prevent the heat spreading member and the electronic component from camber even if heat is applied to the heat spreading member and the electronic component. Separation is thus avoided between the heat spreading member and the electronic component. The heat spreading member reliably keeps contacting with the electronic component, so that the electronic component package is allowed to enjoy improvement in heat radiation.
