Abstract: PROBLEM TO BE SOLVED: To provide an electronic package and a method of manufacturing the electronic package. SOLUTION: A package 10 is provided with a semiconductor chip 12 and a multilayer interconnection structure 18 having an allyl surface layer. The semiconductor chip 12 has a plurality of contact members 16 on one surface, and is connected with the inside of the multilayer interconnection structure 18 by using a plurality of solder connecting members 20. The multilayer interconnection structure 18 is constituted so as to electrically and interconnect circuits of a board 100 by using a plurality of other solder connecting members 47 and has a heat conduction layer 22 composed of material having a selected thickness and coefficient of thermal expansion with which solder connecting obstruction between a plurality of first conducting members and the semiconductor chip is prevented totally. The electronic package 10 includes dielectric material having effective tensile stress for ensuring sufficient compliancy with the multilayer interconnection structure 18 during operation. The allyl surface layer has characteristic capable of enduring thermal stress which is generated during heat cycle operation of the electronic package 10.
