Provided is a breathable structure, in which: a luer lock cap (1) is made of synthetic resin having a low melting point, including a through-hole (11) to be covered with a breathable film (2); the breathable film (2) is a two-layered film made of synthetic resin having breathability, in which a second film (22) having a low melting point adheres to a porous first film (21) having water repellency; an auxiliary film body (3) is a two-layered film made of synthetic resin with an outer shape larger than an outer shape of the breathable film (2), in which a fourth film (32) having a melting point higher than a melting point of a third film (31) having a low melting point adheres to the third film (31); the breathable film (2) is connected to the auxiliary film body (3) with the second film (22) being heat-laminated to the third film (31) so that the breathable film (2) does not extend beyond the auxiliary film body (3); and the auxiliary film body (3) is connected to the luer cap lock (1) with an outer edge portion of the third film (31) being heat-laminated to the luer cap lock (1). |
