4
, which is an open frame fitting the height and width of the remote-controller
2
to be protected. The protective cover
3
comprises a peripheral strip
31
, a transparent top panel
32
, and a transparent bottom panel
33
. The peripheral strip
31
, the transparent top panel
32
, and the transparent bottom panel
33
are respectively cut from transparent sheet material, for example, PVC (polyvinyl chloride) sheet material. The two ends of the peripheral strip
31
are sealed together, forming a loop. An insertion slot
311
is formed in one end of the loop-like peripheral strip
31
. The loop-like peripheral strip
31
fits the inner diameter of the mold
4
. After preparation, the loop-like peripheral strip
31
is put in the mold
4
and closely attached to the inside wall of the mold
4
, and then the mold
4
with the loop-like peripheral strip
31
are put on the bottom panel
33
in a high-frequency heat sealing machine, and then the border of the bottom panel
33
is heat-sealed to the border of the bottom side of the loop-like peripheral strip
31
by the high-frequency heat sealing machine, and then the top panel
32
is covered on the mold
4
over the border of the top side of the loop-like peripheral strip
31
and heat-sealed to the border of the top side of the top side of the loop-like peripheral strip
31
by the high-frequency heat sealing machine. During sealing, the protruding portions of the loop-like peripheral strip
31
, the top panel
32
and the bottom panel
33
outside the seal area are simultaneously cut away by the top and bottom cutting edges of the mold
4
. After sealing, the desired protective cover
3
is obtained, which fits the shape of the remote controller
2
. Through the insertion slot
311
, the remote controller
2
is inserted into the inside of the protective cover
3
.
