PROBLEM TO BE SOLVED: To prevent adherence of a lid body and a container main body in an unbonded part, by providing the heat-bonded part of the peripheral edge parts of a blister package with the unbonded part serving as an unsealing initiation end and by forming projections sticking out on the contents storage side onto the container main body in the unbonded part. SOLUTION: A package body comprises a lid body 2 and a container main body 3, and a drawing part is formed in the container main body 3. Contents are stored in the drawing part, and all the part except the drawing part and an unsealing initiation end provided in one of the corners of the package body, are heat-bonded to the lid body 2. On the container main body 3 at the unsealing initiation end 4, cylindrical projections 8 sticking out on the side of the drawing part are formed. This provides an unbonded part where the lid body and container main body at the unsealing initiation end do not partially adhere to each other, and enables the easy separation of the lid body and container main body and the easy formation of a part for causing the unsealing of the package body.
