• a first seal member arranged on a bottom surface of the recess portion, and mounting the signal line;
• a second seal member including a gelatinous composition arranged to cover the signal line arranged on the first seal member;
• and
• a third seal member arranged between the first and second cases, and pushing the second case.

A portable device comprising an seal structure sealing a housing for passing a signal line therethrough, the seal structure comprising:

• a first case;
• a second case joined to the first case to define the housing, and provided with a recess portion through which the signal line passes at a joining surface joining the first case;
• a first seal member arranged on a bottom surface of the recess portion, and mounting the signal line;
• a second seal member including a gelatinous composition arranged to cover the signal line arranged on the first seal member;
• and
• a third seal member arranged between the first and second cases, and pushing the second case.

A seal method comprising:

• arranging a second case provided at its joining surface facing the first case with a recess portion through which a signal line passes;
• adhering a first seal member on a bottom surface of the recess portion;
• adhering the signal line to the first seal member;
• arranging a second seal member including a gelatinous composition to cover the signal line;
• joining the first and second cases while a third seal member arranged between the first and second cases is pushing the second case.
