1. A battery pack, comprising:
a battery cell including a terrace portion from which an electrode is drawn out;
a protection module package electrically connected to the battery cell; and
an input/output line,
wherein the protection module package includes:
an insulating frame including:
a base portion on the terrace portion of the battery cell, and
a first partition wall extending vertically from an edge of the base portion and facing the battery cell such that the first partition wall extends in a plane perpendicular to a plane of the base portion,
a circuit portion on the insulating frame, and
an insulating block covering only a portion of the circuit portion such that the covered portion of the circuit portion is between the base portion and the insulating block and uncovered portions of the circuit portion are at sides of the insulating block in a first direction, the first direction being a lengthwise direction of the terrace portion,
wherein:
the circuit portion includes:
a circuit board, the circuit board being a support base of the circuit portion,
a connection tab on the circuit board and connected to the electrode of the battery cell, and
a safety element on the circuit board and connected to the connection tab,
the circuit board includes a connection region protruding in a second direction intersecting with the first direction,
the base portion of the insulating frame includes a protruding region protruding in the second direction in parallel with the connection region and supporting the connection region,
the input/output line is connected to the connection region of the circuit board,
the input/output line extends between the connection region of the circuit board and the base portion,
the connection region protrudes from a central position of the circuit board, the central position of the circuit board being at a center of the circuit board in the first direction, and
the insulating block covers both the safety element and the connection region,
wherein the insulating block is separated from the insulating frame with the circuit board therebetween, and
the insulating block covers an entire outer surface of the safety element except for a bottom of the safety element, which is connected to the circuit board.
